◆ CThreadedApp() CThreadedApp::CThreadedApp ( void  ) ◆ Init() void CThreadedApp::Init ( void  ) privatevirtual

Initialize the app.

Reimplemented from CNcbiApplicationAPI.

◆ Run() int CThreadedApp::Run ( void  ) privatevirtual

Run the threads.

Implements CNcbiApplicationAPI.

◆ SetNumberOfDelayedStartSyncPoints() void CThreadedApp::SetNumberOfDelayedStartSyncPoints ( unsigned int  num_min, unsigned int  num_max  ) protected ◆ TestApp_Args()

Override this method to add your custom arguments.

Returns
TRUE on success, and FALSE on failure.

Definition at line 755 of file test_mt.cpp.

◆ TestApp_DelayedStartSyncPoint() void CThreadedApp::TestApp_DelayedStartSyncPoint ( const string &  name ) protected

Start threads that belong to delayed group (this call may be ignored to provide more randomness).

Note
anywhere in the middle.
Parameters
name Name can be anything you like, providing other threads use the same name. The test application distinguishes delayed-start sync points by name.

◆ TestApp_Exit() bool CThreadedApp::TestApp_Exit ( void  ) protectedvirtual

Override this method to execute code after all threads terminate.

Returns
TRUE on success, and FALSE on failure.

Definition at line 811 of file test_mt.cpp.

Referenced by CThreadedApp::Run().

◆ TestApp_GlobalSyncPoint() void CThreadedApp::TestApp_GlobalSyncPoint ( void  ) protected

Wait until ALL threads reach a call of TestApp_GlobalSyncPoint().

Warning
You can use this method if you want threads to be synchronized across different branches of code. The only thing to keep in mind is that EVERY thread has to reach TestApp_GlobalSyncPoint() for execution to be continued.
Note
Calling TestApp_GlobalSyncPoint() automatically awakes all threads that would be otherwise awaken only with TestApp_DelayedStartSyncPoint().

◆ TestApp_Init() bool CThreadedApp::TestApp_Init ( void  ) protectedvirtual
