NAME
pthread_attr_getschedparam -- get and set scheduling attributes
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h> int pthread_attr_getschedparam(const pthread_attr_t * restrict attr, struct sched_param * restrict param); int pthread_attr_setschedparam(pthread_attr_t *attr, const struct sched_param *param); int pthread_attr_getschedpolicy(const pthread_attr_t * restrict attr, int * restrict policy); int pthread_attr_setschedpolicy(pthread_attr_t *attr, int policy);
DESCRIPTION
The pthread_attr_getschedparam() and pthread_attr_setschedparam() func- tions obtain and set the scheduling parameter attribute in the attr object. The sched_param structure is defined in <sched.h>. At minimum this structure contains only a single member, sched_priority. Refer to pthread_schedparam(3) and sched(3) for additional details. The pthread_attr_getschedpolicy() and pthread_attr_setschedpolicy() func- tions get and set the scheduling policy attribute, policy, in the attr object. The supported values of policy are the same ones listed in pthread_schedparam(3).
RETURN VALUES
If successful, all described functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
The pthread_attr_getschedparam() function may fail if: [EINVAL] An invalid parameter was specified. The pthread_attr_setschedparam() function may fail if: [EINVAL] An invalid parameter was specified. [ENOMEM] There was insufficient memory. The pthread_attr_setschedpolicy() function may fail if: [ENOMEM] There was insufficient memory. [ENOTSUP] An unsupported policy was specified. No errors are defined for pthread_attr_getschedpolicy().
