posix_getrlimit
POSIX_GETRLIMIT(3) 1 POSIX_GETRLIMIT(3)posix_getrlimit - Return info about system resource limitsSYNOPSIS
array posix_getrlimit (void )
DESCRIPTION posix_getrlimit(3) returns an array of information about the current resource's soft and hard limits.
Each resource has an associated soft and hard limit. The soft limit is the value that the kernel enforces for the corresponding resource.
The hard limit acts as a ceiling for the soft limit. An unprivileged process may only set its soft limit to a value from 0 to the hard
limit, and irreversibly lower its hard limit.
RETURN VALUES
Returns an associative array of elements for each limit that is defined. Each limit has a soft and a hard limit.
