POSIX_SPAWNATTR_GETSIGMASK(3) | Library Functions Manual | POSIX_SPAWNATTR_GETSIGMASK(3)

# NAME

`posix_spawnattr_getsigmask`, `posix_spawnattr_setsigmask` —
get and set the spawn-sigmask attribute of a spawn attributes object

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

`#include <spawn.h>`

int
`posix_spawnattr_getsigmask`(const posix_spawnattr_t *restrict attr, sigset_t *restrict sigmask);

int
`posix_spawnattr_setsigmask`(posix_spawnattr_t *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

The `posix_spawnattr_getsigmask`() and `posix_spawnattr_setsigmask`() functions return zero.

# SEE ALSO

# STANDARDS

The `posix_spawnattr_getsigmask`() and `posix_spawnattr_setsigmask`() functions conform to IEEE Std 1003.1-2001 (“POSIX.1”).

# HISTORY

The `posix_spawnattr_getsigmask`() and `posix_spawnattr_setsigmask`() functions first appeared in FreeBSD 8.0 and imported for NetBSD 6.0.
