Detailed Description

The Wefts++ namespace.

All the wefts classes and functions are available under Wefts namespce; 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 );
   }

Function Documentation

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().

bool Wefts::Sleep (  double    seconds )

Sleeps a certain amount of time. Sleeps for a given amount of seconds (1.0 meaning one second, 0.5 half second and so on). The process calling this function will be awaken as soon as possible as the time is elapsed; this could also result in a noticeable delay. Also, it is possible that the process is awaken before the wait is elapsed; this may happen if a signal is issued to the process that is currently helding waiting threads. Note: Even if you use the command using namespace Wefts, this function won't clash with MS-Windows API Sleep(), as their prototype are different. Just remember that if you want to invoke Wefts::Sleep(), you have to use double parameter, that is dotted numbers as 1.0, never 1. Parameters: seconds  the wait time in seconds and second fractions. Returns: true if wait has elapsed without interruption, false otherwise.

bool Wefts::Sleep (  long    seconds, long    nanoseconds )

Sleeps a certain amount of time. Sleeps for a given amount of seconds (that may be also 0), and of nanoseconds (up to 999,999,999, almost one second). The process calling this function will be awaken as soon as possible as the time is elapsed; this could also result in a noticeable delay. Also, it is possible that the process is awaken before the wait is elapsed; this may happen if a signal is issued to the process that is currently helding waiting threads. Parameters: seconds  the wait time in whole seconds (may be 0) nanoseconds  wait time in nanoseconds ( up to one second). Returns: true if wait has elapsed without interruption, false otherwise.

Counter startedThreads (  1    )

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