PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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.
