PTHREAD_SETSCHEDPRIO(3) Linux Programmer's ManualPTHREAD_SETSCHEDPRIO(3)
pthread_setschedprio - set scheduling priority of a thread
#include <pthread.h>
int 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 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.
For an explanation of the terms used in this section, see
attributes(7).
