- get or set inheritsched attribute
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);
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:
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.
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>.
If successful, the pthread_attr_setinheritsched() and pthread_attr_getinheritsched() functions return 0. Otherwise, an error number is returned to indicate the error.
The pthread_attr_setinheritsched() or pthread_attr_getinheritsched() functions may fail if:
attr or inheritsched is invalid.
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.
