Copying the contents of a wxString

[Iulian-Nicu Serbanoiu]

( wxString::Len() + 1 ) * sizeof(wxChar). That's unicode
representation, as wxChar can represent any character from the unicode
tables.

Your buffer could be wxChar * ( or char * if you want all contents ).

wxString str;
...
int wxchar_len = str.Len()+1;
wxChar * buf = new wxChar[wxchar_len];
memcpy(buf,str.c_str(),wxchar_len*sizeof(wxChar) );

// and

int char_len = wxchar_len*sizeof(wxChar)/sizeof(char);

char * buf  = new char[char_len];
memcpy( buf , str.c_str() , char_len*sizeof(char) );

Hope this correct,

Iulian
