Standard C Library Functions pthread_attr_getscope(3C)
NAME
pthread_attr_getscope, pthread_attr_setscope - get or set
contentionscope attributeSYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#include
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 attri-
bute in the attr object. The contentionscope attribute can have the valuePTHREAD_SCOPE_SYSTEM, signifying system scheduling conten-
tion scope, or PTHREAD_SCOPE_PROCESS, signifying process
scheduling contention scope.The symbols PTHREAD_SCOPE_SYSTEM and PTHREAD_SCOPE_PROCESS
are defined by the header. RETURN VALUES
If successful, the pthread_attr_setscope() and
pthread_attr_getscope() functions return 0. Otherwise, an
error number is returned to indicate 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 usingpthread_create(). Using these routines does not affect the
current running thread.ATTRIBUTES
