PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME

       posix_spawnattr_getsigmask, posix_spawnattr_setsigmask — get and
       set the spawn-sigmask attribute of a spawn attributes object
       (ADVANCED REALTIME)

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 shall obtain the value
       of the spawn-sigmask attribute from the attributes object
       referenced by attr.

       The posix_spawnattr_setsigmask() function shall set 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 VALUE

       Upon successful completion, posix_spawnattr_getsigmask() shall
       return zero and store the value of the spawn-sigmask attribute of
       attr into the object referenced by the sigmask parameter;
       otherwise, an error number shall be returned to indicate the
       error.

       Upon successful completion, posix_spawnattr_setsigmask() shall
       return zero; otherwise, an error number shall be 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.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       These functions are part of the Spawn option and need not be
       provided on all implementations.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
