140// ============================================================================

142// A few notes on implementation of these wrappers:
143//
144// We need both char* and wchar_t* versions of functions like wxStrlen() for
145// compatibility with both ANSI and Unicode builds.
146//
147// This makes passing wxString or c_str()/mb_str()/wc_str() result to them
148// ambiguous, so we need to provide overrides for that as well (in cases where
149// it makes sense).
150//
151// We can do this without problems for some functions (wxStrlen()), but in some
152// cases, we can't stay compatible with both ANSI and Unicode builds, e.g. for
153// wxStrcpy(const wxString&), which can only return either char* or wchar_t*.
154// In these cases, we preserve ANSI build compatibility by returning char*.
