<span class="function"><strong>posix_setrlimit()</strong></span> sets the soft and hard limits for a
given system resource.

<p class="para">
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.
