pthread_attr_getinheritsched(3C)			   Standard C Library Functions 			  pthread_attr_getinheritsched(3C)

NAME
pthread_attr_getinheritsched, pthread_attr_setinheritsched - get or set inheritsched attribute
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_attr_getinheritsched(const pthread_attr_t *restrict attr, int *restrict inheritsched); int pthread_attr_setinheritsched(pthread_attr_t *attr, int inheritsched);
DESCRIPTION
The functions pthread_attr_setinheritsched() and pthread_attr_getinheritsched(), respectively, set and get the inheritsched attribute in the attr argument. When the attribute objects are used by pthread_create(), the inheritsched attribute determines how the other scheduling attributes of the created thread are to be set: PTHREAD_INHERIT_SCHED Specifies that the scheduling policy and associated attributes are to be inherited from the creating thread, and the scheduling attributes in this attr argument are to be ignored. PTHREAD_EXPLICIT_SCHED Specifies that the scheduling policy and associated attributes are to be set to the corresponding values from this attribute object. The symbols PTHREAD_INHERIT_SCHED and PTHREAD_EXPLICIT_SCHED are defined in the header <pthread.h>.
RETURN VALUES
If successful, the pthread_attr_setinheritsched() and pthread_attr_getinheritsched() functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
The pthread_attr_setinheritsched() or pthread_attr_getinheritsched() functions may fail if: EINVAL attr or inheritsched is invalid.
USAGE
After these attributes have been set, a thread can be created with the specified attributes using pthread_create(). Using these routines does not affect the current running thread.
