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

NAME
pthread_attr_getscope, pthread_attr_setscope -- thread attribute operations SYNOPSIS
#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
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. The pthread_attr_setscope() and pthread_attr_getscope() functions, respectively, set and get the attribute within attr argument that controls the contention scope of the thread. The acceptable values are PTHREAD_SCOPE_SYSTEM, indicating a scheduling contention scope that is system- wide, and PTHREAD_SCOPE_PROCESS, which indicates a process scheduling contention scope. Currently on Mac OS X we only support PTHREAD_SCOPE_SYSTEM. RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error. ERRORS
pthread_attr_getscope() will fail if: [EINVAL] Invalid value for attr. pthread_attr_setscope() will fail if: [EINVAL] Invalid value for attr. [ENOTSUP] Invalid or unsupported value for contentionscope. SEE ALSO
pthread_create(3), pthread_attr_init(3), pthread_attr_setinheritsched(3), pthread_attr_setschedpolicy(3), pthread_attr_setschedparam(3) STANDARDS
pthread_attr_setscope(), pthread_attr_getscope() conform to Version 2 of the Single UNIX Specification (``SUSv2'') BSD
