the following pertains to solaris 10 -- don't know about other versions
can someone explain how
sysconf(_SC_PASS_MAX) == 256
for these compile options
cc
cc -D_POSIX_SOURCE=1
cc -D_POSIX_C_SOURCE=21000101L
cc -D_POSIX_SOURCE=1 -D_POSIX_C_SOURCE=21000101L
cc -D_XOPEN_SOURCE -D_XOPEN_VERSION=4 <<< "XPG4"
vs.
/usr/bin/getconf PASS_MAX == 256
/usr/xpg4/bin/getconf PASS_MAX == 8 <<< value in question
/usr/xpg6/bin/getconf PASS_MAX == 256
when the getconf(1) standard text specifies
The value of each configuration variable shall be determined as if it
were obtained by calling the function from which it is defined to be
available by this volume of IEEE Std 1003.1-2001 or by the System
Interfaces volume of IEEE Std 1003.1-2001 (see the OPERANDS section).
The value shall reflect conditions in the current operating
environment.
where I assume that this is the function call for PASS_MAX:
sysconf(_SC_PASS_MAX)
does this fall into the "shall reflect conditions in the current
operating environment" hole?
