ulimit
ULIMIT(3) BSD Library Functions Manual ULIMIT(3)
NAME
ulimit -- get and set process limits
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ulimit.h>
long
ulimit(int cmd, ...);
DESCRIPTION
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 will return the maximum file size of the current process, in units of 512-byte blocks.
UL_SETFSIZE will attempt to set the maximum file size of the current process and its children, using the second argument (expressed as a
long).
RETURN VALUES
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.
ERRORS
The ulimit() function will fail if:
[EINVAL] The command specified was invalid.
[EPERM] The limit specified to ulimit() would have raised the maximum limit value, and the caller is not the super-user.
SEE ALSO
getrlimit(2)
STANDARDS
The ulimit() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The ulimit() function first appeared in FreeBSD 5.0.
BUGS
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.
