NAME
pthread_setschedprio - set scheduling priority of a thread
SYNOPSIS
#include <pthread.h>
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.
POSIX.1-2001 also documents an ENOTSUP ("attempt was made to set the
priority to an unsupported value") error for pthread_setschedparam().
VERSIONS
This function is available in glibc since version 2.3.4.
CONFORMING TO
POSIX.1-2001.
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
