PTHREAD_SETSCHEDPRIO(3) Linux Programmer's Manual PTHREAD_SETSCHEDPRIO(3)
pthread_setschedprio - set scheduling priority of a thread
#include <pthread.h>
pthread_setschedprio(pthread_t thread, int prio);
Compile and link with -pthread.
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.)
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.
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.
POSIX.1-2001 also documents an ENOTSUP ("attempt was made to set the priority
to an unsupported value") error for pthread_setschedparam(3).
This function is available in glibc since version 2.3.4.
POSIX.1-2001.
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_setscheduler(2).
