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 follow- ing: UL_GETFSIZE will return the maximum file size in units of 512 blocks of the current process. UL_SETFSIZE will attempt to set the maximum file size of the current process and its children with the second argument expressed as a long. RETURN VALUES Upon successful completion, ulimit() returns the value requested; other- wise the value -1 is returned and the global variable errno is set to in- dicate 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 retriev- ing 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. BSD January 4, 2003 BSD
