Standard C Library Functions    posix_spawnattr_getschedparam(3C)



NAME
     posix_spawnattr_getschedparam, posix_spawnattr_setschedparam
     - get and set spawn-schedparam attribute of spawn attributes
     object

SYNOPSIS
     #include 
     #include 

     int posix_spawnattr_getschedparam(const posix_spawnattr_t *restrict attr,
          struct sched_param *restrict schedparam);


     int posix_spawnattr_setschedparam(posix_spawnattr_t *restrict attr,
          const struct sched_param *restrict schedparam);


DESCRIPTION
     The  posix_spawnattr_getschedparam()  function  obtains  the
     value  of the spawn-schedparam attribute from the attributes
     object referenced by attr.


     The  posix_spawnattr_setschedparam()   function   sets   the
     spawn-schedparam  attribute  in  an  initialized  attributes
     object referenced by attr.


     The spawn-schedparam  attribute  represents  the  scheduling
     parameters  to  be  assigned  to  the new process image in a
     spawn    operation    (if    POSIX_SPAWN_SETSCHEDULER     or
     POSIX_SPAWN_SETSCHEDPARAM  is  set in the spawn-flags attri-
     bute). The default value of this attribute is unspecified.

RETURN VALUES
     Upon successful completion,  posix_spawnattr_getschedparam()
     returns  0  and  stores  the  value  of the spawn-schedparam
     attribute  of  attr  into  the  object  referenced  by   the
     schedparam parameter. Otherwise, an error number is returned
     to indicate the error.


     Upon successful completion,  posix_spawnattr_setschedparam()
     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.
