Is it advisable to use strcmp or _tcscmp for comparing strings in Unicode versions?
_tcscmp() is a macro. If you define UNICODE it will use wcscmp(), otherwise it will use strcmp().
Note the types TCHAR, PTSTR, etc. are similar. They will be WCHAR and PWSTR if you define UNICODE, and CHAR and PSTR otherwise.
No, you should use _tcscmp . That will resolve to proper function depending upon on your compiler flags.
