* Name: posix_spawnattr_getschedparam
|
|
*
|
|
* Description:
|
|
* The posix_spawnattr_getschedparam() function will obtain the value of
|
|
* the spawn-schedparam attribute from the attributes object referenced
|
|
* by attr.
|
|
*
|
|
* Input Parameters:
|
|
* attr - The address spawn attributes to be queried.
|
|
* param - The location to return the spawn-schedparam value.
|
|
*
|
|
* Returned Value:
|
|
* On success, these functions return 0; on failure they return an error
|
|
* number from <errno.h>.
