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.
