POSIX_SPAWNATTR_GETSIGIGNORE_NP(3C) Standard C Library Functions

NAME

posix_spawnattr_getsigignore_np, 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.
