POSIX_SPAWNATTR_GETSI... BSD Library Functions Manual POSIX_SPAWNATTR_GETSI... 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 attri- bute 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() func- tions return zero.

HISTORY The posix_spawnattr_getsigmask() and posix_spawnattr_setsigmask() func- tions first appeared in FreeBSD 8.0. AUTHORS Ed Schouten <ed@FreeBSD.org> BSD March 24, 2008 BSD
