NAME
       PR_SET_MM_BRK - modify kernel memory map descriptor fields


LIBRARY
       Standard C library (libc, -lc)


SYNOPSIS
       #include <linux/prctl.h>  /* Definition of PR_* constants */
       #include <sys/prctl.h>

       int prctl(PR_SET_MM, PR_SET_MM_BRK, unsigned long addr, 0L, 0L);


DESCRIPTION
       Set the current brk(2) value.

       The requirements for the address are the same as for the PR_SET_MM_START_BRK option.


RETURN VALUE
       On success, 0 is returned.  On error, -1 is returned, and errno is set to indicate the error.


ERRORS
       EINVAL addr  is  greater  than  TASK_SIZE  (the  limit  on  the  size  of the user address space for this
              architecture).

       EINVAL addr is less than or equal to the end of the data segment or specifies a value  that  would  cause
              the RLIMIT_DATA resource limit to be exceeded.


STANDARDS
       Linux.


HISTORY
       Linux 3.3.
