posix_spawnattr_setsigmask()

Set the signal mask attribute of a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_setsigmask(
       posix_spawnattr_t *_Restrict attrp,
       const sigset_t *_Restrict sigset_p);

Since:

BlackBerry 10.0.0

Arguments:

attrp
A pointer to the spawn attributes object that you want to modify.
sigset_p
A pointer to the signal mask that you want to store.

Library:

libc

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

Description:

The posix_spawnattr_setsigmask() function sets the signal mask attribute in an initialized attributes object referenced by attrp. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().

The value of this attribute is used as the signal mask in the new process image of a spawn operation if POSIX_SPAWN_SETSIGMASK is set in the spawn flags attribute; to set this flag, call the POSIX function posix_spawnattr_setflags(), or the BlackBerry 10 OS function posix_spawnattr_setxflags(). By default, the mask is an empty signal set.

To retrieve the current value of this attribute, call posix_spawnattr_getsigmask().

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

Returns:

EOK
Success.
EINVAL
An argument was invalid.

Classification:

POSIX 1003.1 SPN

Cancellation point No
Interrupt handler Yes
