    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.
