6 The MLWorks Windows Interface Library

6.7 Identifier reference

Some Windows functions specify the success or failure of their execution by returning a BOOL, int, or DWORD. The equivalent ML functions typically handle failure by raising an exception. As a result such ML functions return a unit, relying on the exception to clarify the nature of the failure. The functions to which this applies are marked as follows:

• Functions marked ¤ return a unit as opposed to BOOL in the Windows equivalent.

• Functions marked return a unit as opposed to int in the Windows equivalent.

• Functions marked return a unit as opposed to DWORD in the Windows equivalent.

• In cases where a Windows function passes a pointer to a structure, the corresponding ML function usually passes the structure itself. Such functions are marked *.
