wxConvUTF8.cWX2MB

[ioio]

This mays be simple but the documentation doesn't answer on that.

This piece of code has been compiled in UNICODE

Code: Select all

wxString str;
// .... we fill str
const char *buffer = wxConvUTF8.cWX2MB( str );
/// ...

Does the buffer have to be freed with free() ?

Hi ioio,

there are two possible scenarios:

You call cWX2MB() in an ansi build. You'll then get back the parameter unaltered.

Or you call cWX2MB() in an Unicode build. You'll then get back a wxCharBuffer, which is an object that can be cast to (const char*). That buffer will be defined as long as the wxCharBuffer object doesn't lose scope, i.e. the surrounding block

Code: Select all

{ // begin block

wxString str;
const char *buffer = wxConvUTF8.cWX2MB( str );

} // end block, losing scope here.

isn't left. To make a long story short: No, you don't have to free it

HTH, Chris
