NAME
pthread_setschedprio - set scheduling priority of a thread
SYNOPSIS
#include <pthread.h>
int pthread_setschedprio(pthread_t thread, int prio);
Compile and link with -pthread.
DESCRIPTION
The pthread_setschedprio() function sets the scheduling priority of the thread thread to the value specified in prio. (By contrast pthread_setschedparam(3) changes both the scheduling policy and priority of a thread.)
RETURN VALUE
On success, this function returns 0; on error, it returns a nonzero error number. If pthread_setschedprio() fails, the scheduling priority of thread is not changed.
ERRORS
| EINVAL | prio is not valid for the scheduling policy of the specified thread. |
| EPERM | The caller does not have appropriate privileges to set the specified priority. |
| ESRCH | No thread with the ID thread could be found. |
VERSIONS
This function is available in glibc since version 2.3.4.

NOTES
For a description of the permissions required to, and the effect of, changing a thread’s scheduling priority, and details of the permitted ranges for priorities in each scheduling policy, see sched(7).
