NAME
     pthread_attr_getinheritsched, pthread_attr_setinheritsched -- thread attribute operations

SYNOPSIS
     #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
     Thread attributes are used to specify parameters to pthread_create().  One attribute object can be used in multiple calls to
     pthread_create(), with or without modifications between calls.

     One of the thread attributes of interest is the "inheritsched" attribute. This attribute controls the scheduling policy and related
     attributes of the newly created thread. The values of the "inheritsched" attribute can be either PTHREAD_INHERIT_SCHED or
     PTHREAD_EXPLICIT_SCHED.

     PTHREAD_INHERIT_SCHED

	  Indicates that the newly created thread should inherit all it's scheduling related attributes from it's creating thread. It ignores the
     values of the relevant attributes within the attr argument.

     PTHREAD_EXPLICIT_SCHED

	  Indicates that the newly created thread should set it's scheduling related attributes based on attr argument.

     The pthread_attr_setinheritsched() functions set the "inheritsched" attribute within the attr argument to the desired value.

     The pthread_attr_getinheritsched() functions copy the value of the "inheritsched" attribute to the location pointed to by the second function
     parameter.

RETURN VALUES
     If successful, these functions return 0.  Otherwise, an error number is returned to indicate the error.

ERRORS
     pthread_attr_getinheritsched() will fail if:

     [EINVAL]		Invalid value for attr.

     pthread_attr_setinheritsched() will fail if:

     [EINVAL]		Invalid value for attr.
