//     wx wrappers for CRT functions in both char* and wchar_t* versions
// ============================================================================

// A few notes on implementation of these wrappers:
//
// We need both char* and wchar_t* versions of functions like wxStrlen() for
// compatibility with both ANSI and Unicode builds.
//
// This makes passing wxString or c_str()/mb_str()/wc_str() result to them
// ambiguous, so we need to provide overrides for that as well (in cases where
// it makes sense).
//
// We can do this without problems for some functions (wxStrlen()), but in some
// cases, we can't stay compatible with both ANSI and Unicode builds, e.g. for
// wxStrcpy(const wxString&), which can only return either char* or wchar_t*.
// In these cases, we preserve ANSI build compatibility by returning char*.

// ----------------------------------------------------------------------------

//     wxSetlocale(category, NULL) -- which is a common thing to do --would be
