PR_SET_MM_MAP(2const)                              PR_SET_MM_MAP(2const)

NAME 

       PR_SET_MM_MAP, PR_SET_MM_MAP_SIZE - 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_MAP,
                 struct prctl_mm_map *map, unsigned long size, 0L);
       int prctl(PR_SET_MM, PR_SET_MM_MAP_SIZE, unsigned int *size, 0L, 0L);

DESCRIPTION 

       PR_SET_MM_MAP
              Provides one-shot access to all the addresses modifyable
              with PR_SET_MM(2const) by passing in a struct prctl_mm_map
              (as defined in <linux/prctl.h>).  The size argument should
              provide the size of the struct.

       PR_SET_MM_MAP_SIZE
              Returns (via the size argument) the size of the struct
              prctl_mm_map the kernel expects.  This allows user space
              to find a compatible struct.

       These features are available only if the kernel is built with the
       CONFIG_CHECKPOINT_RESTORE option enabled.

RETURN VALUE 

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

ERRORS 

       EINVAL The third argument is an invalid address.

STANDARDS 

       Linux.

HISTORY 

       Linux 3.18.
