Standard C Library Functions            pthread_attr_getscope(3C)



NAME
     pthread_attr_getscope, pthread_attr_setscope -  get  or  set
     contentionscope attribute

SYNOPSIS
     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   value
     PTHREAD_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    using
     pthread_create(). Using these routines does not  affect  the
     current running thread.

     See attributes(5) for descriptions of the  following  attri-
