NAME
       pthread_attr_getscope, pthread_attr_setscope - get or set contentionscope attribute

SYNOPSIS
       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_attr_getscope(const pthread_attr_t *restrict attr,
	    int *restrict contentionscope);

       int pthread_attr_setscope(pthread_attr_t *attr, int contentionscope);

DESCRIPTION
       The pthread_attr_setscope() and pthread_attr_getscope() functions are used to set and get the contentionscope attribute in the attr object.

       The   contentionscope   attribute   can	 have	the   value  PTHREAD_SCOPE_SYSTEM,  signifying	system	scheduling  contention	scope,	or
       PTHREAD_SCOPE_PROCESS, signifying process scheduling contention scope.

       The symbols PTHREAD_SCOPE_SYSTEM and PTHREAD_SCOPE_PROCESS are defined by the header <pthread.h>.

RETURN VALUES
       If successful, the pthread_attr_setscope() and pthread_attr_getscope() functions return 0. Otherwise, an error number is returned to  indi-
       cate the error.

ERRORS
       The pthread_attr_setscope(), or pthread_attr_getscope(), function may fail if:

       EINVAL	 attr or contentionscope 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.
