posix_spawnattr

Return the Address Space Layout Randomization (ASLR) setting from a posix_spawn() attribute structure

Synopsis:

#include <spawn.h>

int posix_spawnattr_getaslr(
       const posix_spawnattr_t * attrp,
       posix_spawnattr_aslr_t * aslr);

Arguments:

attrp

A pointer to the opaque spawn attributes object.

aslr

Holds the extracted ASLR setting; one of:

POSIX_SPAWN_ASLR_DEFAULT: The process inherits its parent's settings (equivalent to not setting the attribute).
POSIX_SPAWN_ASLR_ENABLE: Enable ASLR.
POSIX_SPAWN_ASLR_DISABLE: Disable ASLR.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The posix_spawnattr_getaslr() function gets the value of the Address Space Layout Randomization (ASLR) setting in the spawn attributes object that attrp points to. You must have already initialized this object by calling posix_spawnattr_init().

For more information about spawn attributes, see the entry for posix_spawn().

Returns:

EOK: Success.
EINVAL: The handle is not a valid attribute structure.
