PTHREAD_ATTR(3)          BSD Library Functions Manual          PTHREAD_ATTR(3)

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.
