These "should" be ready for inclusion in 5.004, although I'd like to
update Class::Template's doc for legibility. Dean, may we please have
your permission to include this in the distribution?
(I did look a bit into using Class::MethodMaker, but it seemed
a bit complicated.)
I know: these all look remarkably similar on the inside. I keep trying
to find a way to abstract out some of it. Hopefully, they're reasonably
legible at least in code, if not in docs. :-)
Chip/Tim, please check the stat function for proper use of Symbol.
thanks,

=head1 NAME
X
Class::Template - struct/member template builder
X
=head1 EXAMPLES
X
=item * Example 1
X
X use Class::Template;
X
X struct( rusage => {
X ru_utime => timeval,
X ru_stime => timeval,
X });
X
X struct( timeval => [
X tv_secs => '$',
X tv_usecs => '$',
X ]);
X
X my $s = new rusage;
X
=item * Example 2
X
X package OBJ;
X use Class::Template;
X
X members OBJ {
X 'a' => '$',
X 'b' => '$',
X };
X
X members OBJ2 {
X 'd' => '@',
X 'c' => '$',
X };
X
X package OBJ2; @ISA = (OBJ);
X
X sub new {
X my $r = InitMembers( &OBJ::InitMembers() );
X bless $r;
X }
X
=head1 NOTES
X
Use '%' if the member should point to an anonymous hash. Use '@' if the
member should point to an anonymous array.
X
When using % and @ the method requires one argument for the key or index
into the hash or array.
X
Prefix the %, @, or $ with '*' to indicate you want to retrieve pointers to
the values rather than the values themselves.

File::stat.pm - by-name interface to Perl's built-in stat() functions
X
=head1 SYNOPSIS
X
X use File::stat;
X $st = stat($file) or die "No $file: $!";
X if ( ($st->mode & 0111) && $st->nlink > 1) ) {
X print "$file is executable with lotsa links\n";
X }
X
X use File::stat qw(:FIELDS);
X stat($file) or die "No $file: $!";
X if ( ($st_mode & 0111) && $st_nlink > 1) ) {
X print "$file is executable with lotsa links\n";
X }
X
=head1 DESCRIPTION
X
This module's default exports override the core stat()
and lstat() functions, replacing them with versions that return
"File::stat" objects. This object has methods that
return the similarly named structure field name from the
stat(2) function; namely,
dev,
ino,
mode,
nlink,
uid,
gid,
rdev,
size,
atime,
mtime,
ctime,
blksize,
and
blocks.
X
You may also import all the structure fields directly into your namespace
as regular variables using the :FIELDS import tag. (Note that this still
overrides your stat() and lstat() functions.) Access these fields as
variables named with a preceding C<st_> in front their method names.
Thus, C<$stat_obj-E<gt>dev()> corresponds to $st_dev if you import
the fields.
X
To access this functionality without the core overrides,
pass the C<use> an empty import list, and then access
function functions with their full qualified names.
On the other hand, the built-ins are still available
via the C<CORE::> pseudo-package.
X
=head1 NOTE
X
While this class is currently implemented using the Class::Template
module to build a struct-like class, you shouldn't rely upon this.

=head1 NAME
X
Net::hostent - by-name interface to Perl's built-in gethost*() functions
X
=head1 SYNOPSIS
X
X use Net::hostnet;
X
=head1 DESCRIPTION
X
This module's default exports override the core gethostbyname() and
gethostbyaddr() functions, replacing them with versions that return
"Net::hostent" objects. This object has methods that return the similarly
named structure field name from the C's hostent structure from F<netdb.h>;
namely name, aliases, addrtype, length, and addresses. The aliases and
addresses methods return array reference, the rest scalars. The addr
method is equivalent to the zeroth element in the addresses array
reference.
X
You may also import all the structure fields directly into your namespace
as regular variables using the :FIELDS import tag. (Note that this still
overrides your core functions.) Access these fields as variables named
with a preceding C<h_>. Thus, C<$host_obj-E<gt>name()> corresponds to
$h_name if you import the fields. Array references are available as
regular array variables, so for example C<@{ $host_obj-E<gt>aliases()
}> would be simply @h_aliases.
X
The gethost() funtion is a simple front-end that forwards a numeric
argument to gethostbyaddr() by way of Socket::inet_aton, and the rest
to gethostbyname().
X
To access this functionality without the core overrides,
pass the C<use> an empty import list, and then access
function functions with their full qualified names.
On the other hand, the built-ins are still available
via the C<CORE::> pseudo-package.
X
=head1 EXAMPLES
X
X use Net::hostent;
X use Socket;
X
X @ARGV = ('netscape.com') unless @ARGV;
X
X for $host ( @ARGV ) {
X
X unless ($h = gethost($host)) {
X warn "$0: no such host: $host\n";
X next;
X }
X
X printf "\n%s is %s%s\n",
X $host,
X lc($h->name) eq lc($host) ? "" : "*really* ",
X $h->name;
X
X print "\taliases are ", join(", ", @{$h->aliases}), "\n"
X if @{$h->aliases};
X
X if ( @{$h->addr_list} > 1 ) {
X my $i;
X for $addr ( @{$h->addr_list} ) {
X printf "\taddr #%d is [%s]\n", $i++, inet_ntoa($addr);

Net::netent - by-name interface to Perl's built-in getnet*() functions
X
=head1 SYNOPSIS
X
X use Net::netent qw(:FIELDS);
X getnetbyname("loopback") or die "bad net";
X printf "%s is %08X\n", $n_name, $n_net;
X
X use Net::netent;
X
X $n = getnetbyname("loopback") or die "bad net";
X { # there's gotta be a better way, eh?
X @bytes = unpack("C4", pack("N", $n->net));
X shift @bytes while @bytes && $bytes[0] == 0;
X }
X printf "%s is %08X [%d.%d.%d.%d]\n", $n->name, $n->net, @bytes;
X
=head1 DESCRIPTION
X
This module's default exports override the core getnetbyname() and
getnetbyaddr() functions, replacing them with versions that return
"Net::netent" objects. This object has methods that return the similarly
named structure field name from the C's netent structure from F<netdb.h>;
namely name, aliases, addrtype, and net. The aliases
method returns an array reference, the rest scalars.
X
You may also import all the structure fields directly into your namespace
as regular variables using the :FIELDS import tag. (Note that this still
overrides your core functions.) Access these fields as variables named
with a preceding C<n_>. Thus, C<$net_obj-E<gt>name()> corresponds to
$n_name if you import the fields. Array references are available as
regular array variables, so for example C<@{ $net_obj-E<gt>aliases()
}> would be simply @n_aliases.
X
The getnet() funtion is a simple front-end that forwards a numeric
argument to getnetbyaddr(), and the rest
to getnetbyname().
X
To access this functionality without the core overrides,
pass the C<use> an empty import list, and then access
function functions with their full qualified names.
On the other hand, the built-ins are still available
via the C<CORE::> pseudo-package.
X
=head1 EXAMPLES
X
The getnet() functions do this in the Perl core:
X
X sv_setiv(sv, (I32)nent->n_net);
X
The gethost() functions do this in the Perl core:
X
X sv_setpvn(sv, hent->h_addr, len);
X
That means that the address comes back in binary for the
host functions, and as a regular perl integer for the net ones.
This seems a bug, but here's how to deal with it:
X
X use strict;
X use Socket;
X use Net::netent;
X
X @ARGV = ('loopback') unless @ARGV;
X
X my($n, $net);
X
X for $net ( @ARGV ) {
X
X unless ($n = getnetbyname($net)) {
X warn "$0: no such net: $net\n";
X next;
X }
X
X printf "\n%s is %s%s\n",
X $net,
X lc($n->name) eq lc($net) ? "" : "*really* ",
X $n->name;
X
X print "\taliases are ", join(", ", @{$n->aliases}), "\n"
X if @{$n->aliases};
X
X # this is stupid; first, why is this not in binary?
X # second, why am i going through these convolutions
X # to make it looks right
X {
X my @a = unpack("C4", pack("N", $n->net));
X shift @a while @a && $a[0] == 0;
X printf "\taddr is %s [%d.%d.%d.%d]\n", $n->net, @a;
X }
X
X if ($n = getnetbyaddr($n->net)) {
X if (lc($n->name) ne lc($net)) {
X printf "\tThat addr reverses to net %s!\n", $n->name;
X $net = $n->name;
X redo;
X }
X }
X }

module to build a struct-like class, you shouldn't rely upon this.

addressable just like's C's tm structure from F<time.h>; namely with sec,
min, hour, mday, mon, year, wday, yday, and isdst.
X
This class is an internal interface only.

User::grent.pm - by-name interface to Perl's built-in getgr*() functions
X
=head1 SYNOPSIS
X
X use User::grent;
X $gr = getgrgid(0) or die "No group zero";
X if ( $gr->name eq 'wheel' && @{$gr->members} > 1 ) {
X print "gid zero name wheel, with other members";
X }
X
X use User::grent qw(:FIELDS;
X getgrgid(0) or die "No group zero";
X if ( $gr_name eq 'wheel' && @gr_members > 1 ) {
X print "gid zero name wheel, with other members";
X }
X
X $gr = getgr($whoever);
X
=head1 DESCRIPTION
X
This module's default exports override the core getgrent(), getgruid(),
and getgrnam() functions, replacing them with versions that return
"User::grent" objects. This object has methods that return the similarly
named structure field name from the C's passwd structure from F<grp.h>;
namely name, passwd, gid, and members (not mem). The first three
return scalars, the last an array reference.
X
You may also import all the structure fields directly into your namespace
as regular variables using the :FIELDS import tag. (Note that this still
overrides your core functions.) Access these fields as variables named
with a preceding C<gr_>. Thus, C<$group_obj-E<gt>gid()> corresponds
to $gr_gid if you import the fields. Array references are available as
regular array variables, so C<@{ $group_obj-E<gt>members() }> would be
simply @gr_members.
X
The getpw() funtion is a simple front-end that forwards
a numeric argument to getpwuid() and the rest to getpwnam().
X
To access this functionality without the core overrides,
pass the C<use> an empty import list, and then access
function functions with their full qualified names.
On the other hand, the built-ins are still available
via the C<CORE::> pseudo-package.
X
=head1 NOTE
X
While this class is currently implemented using the Class::Template
module to build a struct-like class, you shouldn't rely upon this.

Subject: 10+ debugger patch
Date: Sun, 1 Dec 1996 06:37:31 -0500 (EST)
From: Ilya Zakharevich <ilya@math.ohio-state.edu>
Files: lib/perl5db.pl perl.c pod/perldebug.pod
Bugs corrected:
perl.c
a) Could have deadlocked debugging its own signal handler;
lib/perl5db.pl
pod/perldebug.pod
b) Documentation (internal and POD) updated;
c) NonStop now will not stop at end;
d) variable names more meaningful now;
e) Will not trace last line of itself now;
f) Dumping of looong lines in a program (see Config.pm) interruptable;
g) $@ not wiped by evalled expressions;
While updating the docs I was forced to change some API (to make it
documentable), which resulted in following improvements:
frame & 4 recognized: more verbose output;
frame changes style of TRACE;
Non-interruptable lines have no `:' in the listing;
frame outputs `require'd packages as well.
added Options AutoTrace inhibit_exit
Though this may look a lot, all the changes are not in the main flow
of execution (in frills which are usually disabled), so I think they
may be added even this late in the cycle. Documentation would be quite
messy without these changes.
As well as I know, the documentation is complete now, so one can
_really_ write a new debugger from scratch.
Enjoy,

If it receives any +parameters, they are passed to C<FileHandle::open>; if the open fails, +the C<FileHandle> object is destroyed. Otherwise, it is returned to +the caller. + +C<FileHandle::new_from_fd> creates a C<FileHandle> like C<new> does. +It requires two parameters, which are passed to C<FileHandle::fdopen>; +if the fdopen fails, the C<FileHandle> object is destroyed. +Otherwise, it is returned to the caller. + +C<FileHandle::open> accepts one parameter or two. With one parameter, +it is just a front end for the built-in C<open> function. With two +parameters, the first parameter is a filename that may include +whitespace or other special characters, and the second parameter is +the open mode, optionally followed by a file permission value. + +If C<FileHandle::open> receives a Perl mode string (">", "+<", etc.) +or a POSIX fopen() mode string ("w", "r+", etc.), it uses the basic +Perl C<open> operator. + +If C<FileHandle::open> is given a numeric mode, it passes that mode +and the optional permissions value to the Perl C<sysopen> operator. +For convenience, C<FileHandle::import> tries to import the O_XXX +constants from the Fcntl module. If dynamic loading is not available, +this may fail, but the rest of FileHandle will still work. + +C<FileHandle::fdopen> is like C<open> except that its first parameter +is not a filename but rather a file handle name, a FileHandle object, +or a file descriptor number. + +If the C functions fgetpos() and fsetpos() are available, then +C<FileHandle::getpos> returns an opaque value that represents the +current position of the FileHandle, and C<FileHandle::setpos> uses +that value to return to a previously visited position. + +If the C function setvbuf() is available, then C<FileHandle::setvbuf> +sets the buffering policy for the FileHandle. The calling sequence +for the Perl function is the same as its C counterpart, including the +macros C<_IOFBF>, C<_IOLBF>, and C<_IONBF>, except that the buffer +parameter specifies a scalar variable to use as a buffer.
