Following are three solutions for preventing this type conflict (and the C compiler warnings or C++ compiler errors that would result):

- Use the default behavior. Tchar.h provides generic-text routine prototypes for routines in the run-time libraries, as in the following example.

This method causes an inline function thunk, provided in Tchar.h, to map the generic-text routine directly to the appropriate MBCS routine. The following code excerpt from Tchar.h provides an example of how this is done.

This approach provides a fast alternative if you do not want to use the default behavior or cannot use inlining. It causes the generic-text routine to be mapped by a macro directly to the MBCS version of the routine, as in the following example from Tchar.h.
