135// wx wrappers for CRT functions in both char* and wchar_t* versions
136// ============================================================================
137
138// A few notes on implementation of these wrappers:
139//
140// We need both char* and wchar_t* versions of functions like wxStrlen() for
141// compatibility with both ANSI and Unicode builds.
142//
143// This makes passing wxString or c_str()/mb_str()/wc_str() result to them
144// ambiguous, so we need to provide overrides for that as well (in cases where
145// it makes sense).
146//
147// We can do this without problems for some functions (wxStrlen()), but in some
148// cases, we can't stay compatible with both ANSI and Unicode builds, e.g. for
149// wxStrcpy(const wxString&), which can only return either char* or wchar_t*.
150// In these cases, we preserve ANSI build compatibility by returning char*.
