ulimit - get and set user limits
Návod, kniha: Linux Programmer's Manual
#include <ulimit.h>
long ulimit(int cmd, long newlimit);
Warning: This routine is obsolete. The include file is no longer provided by
glibc. Use getrlimit(2), setrlimit(2) and sysconf(3) instead. For the shell
command
ulimit, see
bash(1).
The
ulimit call will get or set some limit for the current process. The
cmd argument can have one of the following values.
- UL_GETFSIZE
- Return the limit on the size of a file, in units of 512
bytes.
- UL_SETFSIZE
- Set the limit on the size of a file.
- 3
- (Not implemented for Linux.) Return the maximum possible
address of the data segment.
- 4
- (Implemented but no symbolic constant provided.) Return the
maximum number of files that the calling process can open.
On success,
ulimit returns a nonnegative value. On error, -1 is returned,
and
errno is set appropriately.
- EPERM
- A non-root process tried to increase a limit.
SVID.
