Remember that there is a hidden -fork in open(F, "-|") and open(F, "|-"). - -config.sh (Config.pm) lies. It shows d_fork='undef' even though it is -available in perl5x.exe.

Perl5x.exe correctly -returns the process id. - -OS/2 does not have a true exec API (which is used both by the exec -function and when opening a command pipe with perl5x.exe). What -actually happens is the call of a subprocess with the father waiting -for the termination of its child. While waiting, the father still owns -all its resources (it passes signals to the child however) and there -may be some other side effects as well. - ------------------------------------------------------------------------------ -OS2::REXX Module (external library): ------------------------------------- - -NOTE: By default, the REXX variable pool is not available, neither to -Perl, nor to external REXX functions. To enable it, you have to start -Perl with the switch -R, which makes Perl call its interpreter through -REXX. REXX functions which do not use variables may be usable even -without -R though. - -Load REXX DLL: - - $dll = load OS2::REXX NAME [, WHERE]; - - NAME is DLL name, without path and extension. - - Directories are searched WHERE first (list of dirs), then - environment paths PERL5REXX, PERLREXX or, as last resort, PATH. - - The DLL is not unloaded when the variable dies. - - Returns DLL object reference, or undef on failure. - -Define function prefix: - - $dll->prefix(NAME); - - Define the prefix of external functions, prepended to the - function names used within your program, when looking for - the entries in the DLL. - - Example: - $dll = load OS2::REXX "RexxBase"; - $dll->prefix("RexxBase_"); - $dll->Init(); - is the same as - $dll = load OS2::REXX "RexxBase"; - $dll->RexxBase_Init(); - -Define queue: - - $dll->queue(NAME); - - Define the name of the REXX queue passed to all external - functions of this module. Defaults to "SESSION". - -Check for functions (optional): - - BOOL = $dll->find(NAME [, NAME [, ...]]); - - Returns true if all functions are available. - -Call external REXX function: - - $dll->function(arguments); - - Returns the return string if the return code is 0, else undef. - Dies with error message if the function is not available. - -Bind scalar variable to REXX variable: - - tie $var, OS2::REXX, "NAME"; - -Bind array variable to REXX stem variable: - - tie @var, OS2::REXX, "NAME."; - - Only scalar operations work so far. No array assignments, - no array operations, ... FORGET IT. - -Bind hash array variable to REXX stem variable: - - tie %var, OS2::REXX, "NAME."; - - To access all visible REXX variables via hash array, bind to ""; - - No array assignments. No array operations, other than hash array - operations. Just like the *dbm based implementations. - - For the usual REXX stem variables, append a "." to the name, - as shown above. If the hash key is part of the stem name, for - example if you bind to "", you cannot use lower case in the stem - part of the key and it is subject to character set restrictions. - -Erase individual REXX variables (bound or not): - - OS2::REXX::drop("NAME" [, "NAME" [, ...]]); - -Note that while function and variable names are case insensitive in the -REXX language, function names exported by a DLL and the REXX variables -(as seen by Perl through the chosen API) are all case sensitive! - -Most REXX DLLs export function names all upper case, but there are a -few which export mixed case names (such as RxExtras). When trying to -find the entry point, both exact case and all upper case are searched. -If the DLL exports "RxNap", you have to specify the exact case, if it -exports "RXOPEN", you can use any case. - -To avoid interfering with subroutine names defined by Perl (DESTROY) -or used within the REXX module (prefix, find), it is best to use mixed -case and to avoid lowercase only or uppercase only names when calling -REXX functions. Be consistent. The same function written in different -ways results in different Perl stubs. - -There is no REXX interpolation on variable names, so the REXX variable -name TEST.ONE is not affected by some other REXX variable ONE. And it -is not the same variable as TEXT.one! - -You cannot call REXX functions which are not exported by the DLL. -While most DLLs export all their functions, some, like RxFTP, export -only "...LoadFuncs", which registers the functions within REXX only. - -You cannot call 16-bit DLLs. The few interesting ones I found -(FTP,NETB,APPC) do not export their functions. - -I do not know whether the REXX API is reentrant with respect to -exceptions (signals) when the REXX top-level exception handler is -overridden. So unless you know better than I do, do not access REXX -variables (probably tied to Perl variables) or call REXX functions -which access REXX queues or REXX variables in signal handlers. - -See ext/OS2/REXX/rx*.pl for examples. - ------------------------------------------------------------------------------ -OS2::UPM (external library): ----------------------------- - -UPM constants (see <upm.h>) are exported automatically, functions only -on request. - -(USERID, TYPE) = local_user () - - return local user - -LIST = user_list (REMOTENODE="", REMOTETYPE_UPM_LOCAL) - LIST = 4 items per logged on user - [0] = user id - [1] = remote node name - [2] = remote node type (INT) - [3] = session id (INT) - -(USERID, TYPE) = local_logon () - - do a local logon, PM window, if not already logged on - -BOOL = logon (USERID, PASSWORD, AUTHCHECK=UPM_USER, REMOTENODE="", REMOTETYPE=UPM_LOCAL) -BOOL = logoff (USERID, REMOTENODE="", REMOTETYPE=UPM_LOCAL) - - logon/logoff process (DB2/2) - -BOOL = logon_user (USERID, PASSWORD, REMOTENODE="", REMOTETYPE=UPM_LOCAL) -BOOL = logoff_user (USERID, REMOTENODE="", REMOTETYPE=UPM_LOCAL) - - logon/logoff user - -ERRCODE = error () - - return UPM error code of last failure - -STRING = message (ERRCODE) - - return message text for supplied UPM error code - -Defaults: - REMOTETYPE = UPM_LOCAL - REMOTENODE = "" - AUTHCHECK = UPM_USER - ------------------------------------------------------------------------------ -OS2::FTP (external library): ----------------------------- - -$acct = new FTP "host", "userid", "passwd" [, "acct"] - - Create virtual FTP session - no login. - -FTP::logoff() - - Logoff all sessions. - -($msec, $address) = FTP::ping("host", pktlen); -$msec = FTP::ping($address, pktlen); - - Ping host.

Hash array for functions no - longer required, allows overriding subs like "find". - - DLL entries are case sensitive, try both upper case and - exact case. - -18.12.94 Detect char- and block-devices (stat() hack). Some future - release may probably remove block device support, once - char-device support is built into EMX. - - Fixed perl5db tty check. - -22.12.94 EMX fixlevel 2 exports its exception handler, so now - signals work even when the REXX variable pool is enabled. - - Disabled error and exception popups. - -27.12.94 Case conversions of tied variables cleaned up. - - REXX (REXX.DLL, REXXAPI.DLL) now loaded on demand. - -7.1.95 Fixed Shell module (did not allow more than one argument). - -11.1.95 Accept drive letter as absolute path in do/require/use. - -13.1.95 Larrys memory-leak patches (#1, dated Friday 13). - -26.1.95 fcntl and ioctl were missing. fcntl was explicitly disabled - in its source code (ifndef DOSISH) and the ioctl enabler is - in the wrong place (unixish.h instead of config.sh). - -16.3.95 DosQueryFSAttach (stat hack) may crash the system. Now just - look for /dev/con and /dev/tty. - - Applied "pad_findlex" patch (patches/1). - -23.3.95 Support fork. Two executables, one for DLLs and one for fork. - -24.3.95 5.001 - -13.4.95 Patchlevel "c". - -21.4.95 Truncate names of extension DLLs to 8 chars - Warp no longer - accepts them (2.x did). - -22.4.95 Replaced EMX dirent by my own to get all directory entries - even when HPFS386 is used. Additionally, my implementation - is not restricted in the total size of the directory (a - conflict between Perls memory allocator and the one of the - EMX library DLL). - -27.4.95 Support for fork() disabled system() in DLL version. - -7.5.95 Added Tye McQueen's FileGlob. See File::KGlob*. - -12.5.95 Fixed Cwd. Fixed OS/2 dependencies in MakeMaker, with - a few Config.sh items added (separators, exe-extension). - - Moved UPM and REXX to OS2::. Combined REXXCALL and REXX. - Plain old REXX module is still available as passthru though. - - Perl DLLs now have an underscore appended to avoid name - conflicts with standard OS/2 DLLs (see DynaLoader.pm). - -13.5.95 Added FTP API support (OS2::FTP). - -2.7.95 Applied "official unofficial" patches up to level "m". - The modpods documentation now is in the modules themselves. - -4.7.95 Implement command pipes (my_popen) using fork instead of - standard popen in the fork version (perl5x.exe). While this - is a lot slower, it correctly returns the process id and - supports open(F,"-|") and open(F,"|-"). - - Use the same code for exec(CMD) as for system(CMD). - - Support socket functions (set|get|end)(host|net|proto|serv)ent. |
