Get the signal mask attribute of a spawn attributes object

Synopsis:

#include <spawn.h>

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

Arguments:

attrp
A pointer to the spawn attributes object that you want to query.
sigset_p
A pointer to a location where the routine can store the current value of the signal mask attribute.

Library:

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

Description:

The posix_spawnattr_getsigmask() function retrieves the signal mask attribute from the spawn attributes object referenced by attrp, and stores it in the object pointed to by sigset_p. 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() .

To set the value of this attribute, call posix_spawnattr_setsigmask() .

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

Returns:

EOK
Success.
EINVAL
An argument was invalid.
