jtc c5ff256532 POSIX.2 requires special behavior if the first character of the optstring 
argument is a colon.
Updated the manpage to reflect the above change, and expanded the example to
the one used by the POSIX.2 rationale, as it more clearly explains how
the new behavior is to be used.
The manpage should be rewritten --- it is much more confusing than it
should be.

cgd 41ec5a7f5c adding sysarch() man page 1993-10-12 02:16:33 +00:00
jtc 91ebf777c7 Moved cuserid() from getlogin.c to its own file, cuserid.c. 
getlogin() and cuserid() do very different things, getlogin() is POSIX,
while cuserid() is not (it was removed in the 1990 revision).

jtc 845bf7e773 Helper function _strerror is in the user's namespace, renamed it to 
__strerror().

jtc aed559e85d Make it possible to use machine dependant versions of div and ldiv functions. 
Use the new i386 versions of div and ldiv.
 1993-10-09 00:03:32 +00:00
jtc 479a1c33c9 Provide i386 versions of div and ldiv -- they are simpler than the C versions, 
since the idiv instruction does the right thing wrt truncating towards zero.

jtc e09d2f42db Use "testb %cl,%cl" instead of "cmpb $0,%cl". 
This saves three cycles per character, and reduces the size of the
function by eight bytes (the loop is unrolled eight times).
Thanks to davidg for pointing this out.

jtc 42cce25b89 Use machine dependant version of labs.[cs] if one is present. 
If not one of the enumerated list of machines, use the C language
versions of abs, labs, and atof.
 1993-10-08 00:08:12 +00:00
jtc b3f9f8f6f4 Provide an assembly language version of labs(). 
Since ints and longs are both 32 bits on a i386, we could alias abs()
and labs() together as mycroft did with memmove()/memcpy(), but I'm
waiting on an interpretation ruling to see if it is legal.

jtc 473c152a0a Moved strerror.[c3] from libc/stdio to libc/string. 
Since perror is not permitted to change strerror()'s static buffer, I have
changed both functions to pass their own buffers to the new library-internal
function _strerror() that actually does the error message string look up.
Split strerror manpage into strerror and perror manpages.

cgd eb29ed3995 always create libcrypt, and link with it where necessary. this will 
make life with shared libraries happier.  also, get dummy crypt out
of libc.

jtc c6edc05829 Assembly language version of the swab function. 
This version is only slightly faster than the code generated by gcc on
my i486, but it is almost twice as small.  My i386 timing chart indicates
that this should be significantly faster than the gcc code on a i386.

Surprisingly, none of the code in the source tree actually use this routine.
But I optimized this routine for some image processing programs I wrote, and
I see no reason why everyone else shouldn't share the (admittedly) modest
benifits.
 1993-10-05 18:35:10 +00:00
jtc 20ae84f65b Add swab.c or swab.s, as appropriate, to each machines source list instead 
of always using swab.c

jtc b23776a8de Due to an 8-bit attribute table and 9 bits of attributes, I've had to 
remove the _B attribute from the "horizontal tab" position, and change
the isblank function to explicitly test against space and tab.

When I finish merging the 4.4 runes code, this table will have to grow
to 16 bit entries, as several more attributes have been introduced.
I'm making this change so existing libraries will continue working
for the next (little) while.

jtc 0b5def9bc6 Update to reflect the fact that this manpage is used for both getcwd & getwd: 
Change main title from GETWD to GETCWD as getcwd is the prefered interface.
  Add getwd to NAME section so it shows up in whatis database.
