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