POSIX_SPAWNATTR_GETSIGMASK 3C "Jan 30, 2004"
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.
