NAME
     posix_spawnattr_getsigmask, posix_spawnattr_setsigmask - get
     and set spawn-sigmask attribute of spawn attributes object

SYNOPSIS
     #include 
     #include 

     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 refer-
     enced 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 attri-
     bute of attr into  the  object  referenced  by  the  sigmask
     parameter.   Otherwise, an error number is returned to indi-
     cate the error.


     Upon  successful  completion,   posix_spawnattr_setsigmask()
     returns  0.  Otherwise, an error number is returned to indi-
     cate the error.

ERRORS
     These functions may fail if:

     EINVAL    The value specified by attr is invalid.
