PTHREAD_SCHEDPARAM(3) BSD Library Functions Manual PTHREAD_SCHEDPARAM(3) NAME
pthread_getschedparam, pthread_setschedparam -- thread scheduling parameter manipulation SYNOPSIS
#include <pthread.h> int pthread_getschedparam(pthread_t thread, int *restrict policy, struct sched_param *restrict param); int pthread_setschedparam(pthread_t thread, int policy, const struct sched_param *param); DESCRIPTION
The pthread_getschedparam() and pthread_setschedparam() functions get and set the scheduling parameters of individual threads. The schedul- ing policy for a thread can either be SCHED_FIFO (first in, first out) or SCHED_RR (round-robin). 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_getschedparam() will fail if: [ESRCH] Non-existent thread thread. pthread_setschedparam() will fail if: [EINVAL] Invalid value for policy. [ENOTSUP] Invalid value for scheduling parameters. [ESRCH] Non-existent thread thread. STANDARDS
pthread_setschedparam() and pthread_getschedparam() conform to Version 2 of the Single UNIX Specification (``SUSv2'') BSD

pthread_setschedparam, pthread_getschedparam -- thread scheduling parameter 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 schedul- ing policy 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. SEE ALSO
pthread_attr_getschedparam(3), sched(3) STANDARDS
Both functions conform to IEEE Std 1003.1-2001 (``POSIX.1''). BSD
