[−][src]Function simple_libc::sysconf
pub fn sysconf(name: Int) -> Option<Long>
Get the value of runtime constants/limits.
Given a "name" (one of the libc::_SC_*
constants),
returns the associated configuration value.
None
is returned if an error occurs (usually when
the "name" is not recognized) OR if the value returned
by the C function sysconf()
is < 0 (usually indicates
no limit). To differentiate between these two
possibilities, use sysconf_raw()
.
