NAME
pthread_setschedparam, pthread_getschedparam -- thread scheduling parame- ter manipulation
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h> int pthread_setschedparam(pthread_t thread, int policy, const struct sched_param *param); int pthread_getschedparam(pthread_t thread, int * restrict policy, struct sched_param * restrict param);
DESCRIPTION
The pthread_setschedparam() and pthread_getschedparam() functions set and get the scheduling parameters of individual threads. The scheduling pol- icy for a thread can be: SCHED_FIFO First in, first out. SCHED_RR Round-robin. SCHED_OTHER The system default. The thread priority (accessed via param->sched_priority) must be at least PTHREAD_MIN_PRIORITY and no more than PTHREAD_MAX_PRIORITY.
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
pthread_setschedparam() may fail if: [EINVAL] The value specified by policy is invalid. [ENOTSUP] Invalid value for scheduling parameters. [ESRCH] Non-existent thread thread. pthread_getschedparam() may fail if: [ESRCH] Non-existent thread thread.
