O'Keefe. -Updated: 30 April 1984 -Purpose: Explain the new strings package. - - The UNIX string libraries (described in the string(3) manual page) -differ from UNIX to UNIX (e.g. strtok is not in V7 or 4.1bsd). Worse, -the sources are not in the public domain, so that if there is a string -routine which is nearly what you want but not quite you can't take a -copy and modify it. And of course C programmers on non-UNIX systems -are at the mercy of their supplier. - - This package was designed to let me do reasonable things with C's -strings whatever UNIX (V7, PaNiX, UX63, 4.1bsd) I happen to be using. -Everything in the System III manual is here and does just what the S3 -manual says it does. There are also lots of new goodies. I'm sorry -about the names, but the routines do have to work on asphyxiated-at- -birth systems which truncate identifiers. The convention is that a -routine is called - str [n] [c] <operation> -If there is an "n", it means that the function takes an (int) "length" -argument, which bounds the number of characters to be moved or looked -at. If the function has a "set" argument, a "c" in the name indicates -that the complement of the set is used. Functions or variables whose -names start with _ are support routines which aren't really meant for -general use. I don't know what the "p" is doing in "strpbrk", but it -is there in the S3 manual so it's here too. "istrtok" does not follow -this rule, but with 7 letters what can you do? - - I have included new versions of atoi(3) and atol(3) as well. They -use a new primitive str2int, which takes a pair of bounds and a radix, -and does much more thorough checking than the normal atoi and atol do. -The result returned by atoi & atol is valid if and only if errno == 0. -There is also an output conversion routine int2str, with itoa and ltoa -as interface macros. Only after writing int2str did I notice that the -str2int routine has no provision for unsigned numbers. On reflection, -I don't greatly care. I'm afraid that int2str may depend on your "C" -compiler in unexpected ways. Do check the code with -S. - - Several of these routines have "asm" inclusions conditional on the -VaxAsm option. These insertions can make the routines which have them -quite a bit faster, but there is a snag. The VAX architects, for some -reason best known to themselves and their therapists, decided that all -"strings" were shorter than 2^16 bytes. Even when the length operands -are in 32-bit registers, only 16 bits count. So the "asm" versions do -not work for long strings. If you can guarantee that all your strings -will be short, define VaxAsm in the makefile, but in general, and when -using other machines, do not define it. - - To use this library, you need the "strings.a" library file and the -"strings.h" and "ctypes.h" header files. The other header files are -for compiling the library itself, though if you are hacking extensions -you may find them useful. General users really shouldn't see them. -I've defined a few macros I find useful in "strings.h"; if you have no -need for "index", "rindex", "streql", and "beql", just edit them out. -On the 4.1bsd system I am using declaring all these functions 'extern' -does not mean that they will all be loaded; but only the ones you use. -When using lesser systems you may find it necessary to break strings.h -up, or you could get by with just adding "extern" declarations for the -functions you want as you need them. Many of these functions have the -same names as functions in the "standard C library", by design as this -is a replacement/reimplementation of part of that library. So you may -have to talk the loader into loading this library first. Again, I've -found no problems on 4.1bsd. - - You may wonder at my failure to provide manual pages for this code. -For the things in V7, 4.?, or SIII, you should be able to use whichever -manual page came with that system, and anything I might write would be -so like it as to raise suspicions of violating AT&T copyrights. In the -sources you will find comments which provide far more documentation for -these routines than AT&T ever provided for their strings stuff, I just -don't happen to have put it in nroff -man form. Had I done so, the .3 -files would have outbulked the .c files! - - These files are in the public domain. This includes getopt.c, which -is the work of Henry Spencer, University of Toronto Zoology, who says of -it "None of this software is derived from Bell software. I had no access -to the source for Bell's versions at the time I wrote it. This software -is hereby explicitly placed in the public domain. It may be used for -any purpose on any machine by anyone." I would greatly prefer it if *my* -material received no military use. - |
