//! 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.
