ulimit
— get and
set process limits
Standard C Library (libc, -lc)
#include
<ulimit.h>
long
ulimit
(int cmd,
...);
The
ulimit
()
function will get and set process limits. Currently, this is limited to the
maximum file size. The cmd argument is one of the
following:
UL_GETFSIZE
UL_SETFSIZE
Upon successful completion, ulimit
()
returns the value requested; otherwise, the value -1 is returned and the
global variable errno is set to indicate the
error.
The ulimit
() function will fail if:
The ulimit
() function conforms to
IEEE Std 1003.1-2001 (“POSIX.1”).
The ulimit
() function first appeared in
FreeBSD 5.0.
The ulimit
() function provides limited
precision for setting and retrieving process limits. If there is a need for
greater precision than the type long provides, the
getrlimit(2) and
setrlimit(2) functions should be
considered.
