FUNCTIONS

uname()

Get the name of current operating system.

my ($sysname, $node, $release, $version, $machine) = uname();

Note that the actual meanings of the various fields are not that well standardized: do not expect any great portability. The $sysname might be the name of the operating system, the $nodename might be the name of the host, the $release might be the (major) release number of the operating system, the $version might be the (minor) release number of the operating system, and $machine might be a hardware identifier. Maybe.

CONSTANTS

ARG_MAX       Max bytes of args + env for exec
NGROUPS_MAX
OPEN_MAX      Max # files that one process can have open
TMP_MAX       Min # of unique filenames generated by tmpnam
