File : READ-ME
Author : Richard A. 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.
