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 CON-
FIG_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.
