-.SH NAME
-pthread_setschedprio \- set scheduling priority of a thread
-.SH LIBRARY
-POSIX threads library
-.RI ( libpthread ", " \-lpthread )
-.SH SYNOPSIS
-.nf
-.B #include <pthread.h>
-.P
-.BI "int pthread_setschedprio(pthread_t " thread ", int " prio );
-.fi
-.SH DESCRIPTION
-The
-.BR pthread_setschedprio ()
-function sets the scheduling priority of the thread
-.I thread
-to the value specified in
-.IR prio .
-(By contrast
-.BR pthread_setschedparam (3)
-changes both the scheduling policy and priority of a thread.)
-.\" FIXME . nptl/pthread_setschedprio.c has the following
-.\" /* If the thread should have higher priority because of some
-.\" PTHREAD_PRIO_PROTECT mutexes it holds, adjust the priority. */
-.\" Eventually (perhaps after writing the mutexattr pages), we
-.\" may want to add something on the topic to this page.
-.\" nptl/pthread_setschedparam.c has a similar case.
-.SH RETURN VALUE
-On success, this function returns 0;
-on error, it returns a nonzero error number.
-If
-.BR pthread_setschedprio ()
-fails, the scheduling priority of
-.I thread
-is not changed.
-.SH ERRORS
-.TP
-.B EINVAL
-.I prio
-is not valid for the scheduling policy of the specified thread.
-.TP
-.B EPERM
-The caller does not have appropriate privileges
-to set the specified priority.
-.TP
-.B ESRCH
-No thread with the ID
-.I thread
-could be found.
-.P
-POSIX.1 also documents an
-.B ENOTSUP
-("attempt was made to set the priority
-to an unsupported value") error for
-.BR pthread_setschedparam (3).
