* Name: posix_spawnattr_setschedparam
|
|
*
|
|
* 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.
|
|
*
|
|
* Returned Value:
|
|
* On success, these functions return 0; on failure they return an error
|
|
* number from <errno.h>.
