* Name: sched_getcpu
|
|
*
|
|
* Description:
|
|
* sched_getcpu() returns the number of the CPU on which the calling
|
|
* thread is currently executing.
|
|
*
|
|
* The return CPU number is guaranteed to be valid only at the time of
|
|
* the call. Unless the CPU affinity has been fixed using
|
|
* sched_setaffinity(), the OS might change the CPU at any time. The
|
|
* caller must allow for the possibility that the information returned is
|
|
* no longer current by the time the call returns.
|
|
*
|
|
* Non-Standard. Functionally equivalent to the GLIBC __GNU_SOURCE
|
|
* interface of the same name.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* A non-negative CPU number is returned on success. -1 (ERROR) is
|
|
* returned on failure with the errno value set to indicate the cause of
|
|
* the failure.
|
