typedef Standard_Address(* OSD_ThreadFunction) (Standard_Address data)

Typedef for prototype of function to be used as main function of a thread.

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