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.
