0020 //! Typedef for prototype of function to be used as main function of a thread.
0021 //!
0022 //! Note: currently we use the same prototype for thread functions on all platforms,
0023 //! in order to make user programs less platform-dependent.
0024 //! However, there is a distinction in returned value for the thread function
0025 //! on UNIX/Linux (void*) and Windows (DWORD) systems.
0026 //! Thus on Windows we have to encode returned void* as DWORD.
0027 //! It is OK for WIN32, but potentially problem on WIN64.
0028 //! To avoid any problems with this, for better application portability it is recommended
0029 //! that the thread function returns just integer (casted to void*).
0030 //! This shall work on all platforms.
