, posix_spawnattr_setsigignore_np

- get and set spawn-sigignore attribute of spawn attributes object

Synopsis

#include <signal.h>
#include <spawn.h>

int posix_spawnattr_getsigignore_np(
     const posix_spawnattr_t *restrict attr,
     sigset_t *restrict sigignore);

int posix_spawnattr_setsigignore_np(
     posix_spawnattr_t *restrict attr,
     const sigset_t *restrict sigignore);

Description

The posix_spawnattr_getsigignore_np() function obtains the value of the spawn-sigignore attribute from the attributes object referenced by attr.

The posix_spawnattr_setsigignore_np() function sets the spawn-sigignore attribute in an initialized attributes object referenced by attr.

The spawn-sigignore attribute represents the set of signals to be forced to be ignored in the new process image (if POSIX_SPAWN_SETSIGIGN_NP is set in the spawn-flags attribute) by a spawn operation. The default value of this attribute is an empty signal set.

Return Values

Upon successful completion, posix_spawnattr_getsigignore_np() returns 0 and stores the value of the spawn-sigignore attribute of attr into the object referenced by the sigignore parameter. Otherwise, an error value is returned to indicate the error.

Upon successful completion, posix_spawnattr_setsigignore_np() returns 0. Otherwise, an error value is returned to indicate the error.

Errors

These functions may fail if:

EINVAL

The value specified by attr is invalid.

The posix_spawnattr_setsigignore_np() function may fail if:

EINVAL

The value of the attribute being set is not valid.

Notes

The POSIX_SPAWN_SETSIGIGN_NP flag and the posix_spawnattr_getsigignore_np() and posix_spawnattr_setsigignore_np() functions are non-portable Solaris extensions to the posix_spawn(3C) and posix_spawnp() interfaces.
