|
|
*
|
|
* Description:
|
|
* The posix_spawnattr_setschedparam() function shall set the spawn-

|
* schedparam attribute in an initialized attributes object referenced
|
|
* by attr.
|
|
*
|
|
* Input Parameters:
|
|
* attr - The address spawn attributes to be used.
|
|
* param - The new sched_priority to set.
