ULIMIT(3C)              COMMAND REFERENCE              ULIMIT(3C)



NAME
     ulimit - get and set user limits

SYNOPSIS
     long ulimit (cmd, newlimit)
     int cmd;
     long newlimit;

DESCRIPTION
     This function provides for control over process limits.  The
     cmd values available are:

     1    Get the process's file size limit.  The limit is in
          units of 512-byte blocks and is inherited by child
          processes.  Files of any size can be read.

     2    Set the process's file size limit to the value of
          newlimit.  Any process may decrease this limit, but
          only a process with an effective user ID of superuser
          may increase the limit.  Ulimit will fail and the limit
          will be unchanged if a process with an effective user
          ID other than superuser attempts to increase its file
          size limit.  [EPERM]

     3    Get the maximum possible break value (in bytes).  See
          brk(2).

RETURN VALUE
     Upon successful completion, a nonnegative value is returned.
     Otherwise, a value of -1 is returned and errno is set to
     indicate the error.
