Maximum number of weights that can
be assigned to an entry of the
LC_COLLATE order keyword in a

Itanium-based systems: CPUID
Register 3 of the Itanium-based proces-
sor identification registers. See the
Itanium-based architecture definition
for this platform for the meaning of
each bit.

Maximum parenthesis nesting level for
expr expressions (see expr(1))
EXPR_NEST_MAX _SC_EXPR_NEST_MAX
Maximum getgrgid_r(), getgrnam_r()

GETGR_R_SIZE_MAX _SC_GETGR_R_SIZE_MAX
Maximum getpwuid_r(), getpwnam_r()

GETPW_R_SIZE_MAX _SC_GETPW_R_SIZE_MAX
Returns which kernel is supported on
the hardware. The value returned is
an encoding which may be interpreted
using the
_SYSTEM_SUPPORTS_ILP32OS()
and
_SYSTEM_SUPPORTS_LP64OS()
macros defined in unistd.h. Exam-
ple:
long ret =
sysconf(_SC_HW_32_64_CAPABLE);
if (_SYSTEM_SUPPORTS_ILP32OS(ret)
!= 0) {
/*system supports 32-bit OS*/
}
if (_SYSTEM_SUPPORTS_LP64OS(ret)
!= 0) {
/*system supports 64-bit OS*/
}
