Detailed Description

The Wefts++ namespace.

All the wefts classes and functions are available under Wefts namespace; they are rather thread specific, so if you are using Wefts++ alone, without any other threading library, you will be pretty safe in adding:

   #include <wefts.h>

   using namespace Wefts;

Otherwise, you will have to prefix all Wefts++ calls with the namespace:

   #include <wefts.h>

   int main( int argc, char *argv[] )
   {
      //sleeping a while..
      Wefts::Sleep( 1.5 );
   }

typedef std::pair<CleanupHandler *, int > Wefts::CleanupItem

typedef std::stack< CleanupItem > Wefts::CleanupList

Function Documentation

std::ostream& operator<< (  std::ostream &    stream, Error &    err )

Use this operator to display what kind of error has happened

Counter runningThreads (  1    )

Counter of currently active (or near-to-be active) threads. Initialized to 1: if we initialized it, the main thread is running...

void s_ThreadCleanupper (  void *    param )

Function used (internally) to invoke thread->cleanup() in case of cancelation.

void* s_ThreadRunFunc (  void *    param )

Function used (internally) to invoke thread->run().

void s_ThreadRunner (  void *    data )

Counter startedThreads (  1    )

Incremental counter of started threads. It is used just in internal thread ID count for debugging or reporting purposes
