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.
