attributes.c

用c++包装好的线程库,直接拿来使用,提高效率.

#include "thread.h"

namespace cpp_threads {

  //
  // attributes - constructor
  //
  // initialize the attribute structure with default values.
  attributes::attributes()
  {
    Pthread *p = Pthread::self();
    
    if( !p ||  p->inherit() == attr_explicit_e ) {
      a_scope       = process_private_e;
      a_inherit     = attr_explicit_e;
      a_policy      = rrobin_e;
      a_state       = attr_joinable_e;
    } else {
      a_scope       = p->scope();
      a_inherit     = p->inherit();
      a_policy      = p->policy();
      a_state       = p->joinable()?attr_joinable_e:attr_detached_e;
    }

    a_param.sched_priority = 0;
  }
