posix_spawnattr_getsigmasStandard C Library Funcposix_spawnattr_getsigmask(3C)NAME
posix_spawnattr_getsigmask, posix_spawnattr_setsigmask - get and set
spawn-sigmask attribute of spawn attributes object
SYNOPSIS
#include <signal.h>
#include <spawn.h>
int posix_spawnattr_getsigmask(const posix_spawnattr_t *restrict attr,
sigset_t *restrict sigmask);
int posix_spawnattr_setsigmask(posix_spawnattr_t *restrict attr, const
sigset_t *restrict sigmask);
DESCRIPTION
The posix_spawnattr_getsigmask() function obtains the value of the
spawn-sigmask attribute from the attributes object referenced by attr.
The posix_spawnattr_setsigmask() function sets the spawn-sigmask
attribute in an initialized attributes object referenced by attr.
The spawn-sigmask attribute represents the signal mask in effect in the
new process image of a spawn operation (if POSIX_SPAWN_SETSIGMASK is
set in the spawn-flags attribute). The default value of this attribute
is unspecified.
RETURN VALUES
Upon successful completion, posix_spawnattr_getsigmask() returns 0 and
stores the value of the spawn-sigmask attribute of attr into the object
referenced by the sigmask parameter. Otherwise, an error number is
returned to indicate the error.
Upon successful completion, posix_spawnattr_setsigmask() returns 0.
Otherwise, an error number is returned to indicate the error.
ERRORS
These functions may fail if:
EINVAL The value specified by attr is invalid.
The posix_spawnattr_setsigmask() function may fail if:
EINVAL The value of the attribute being set is not valid.
