I found the code on [http://www.wincli.com/?p=72]. These two functions is what you need: // returns number of TCHARs in string int wstrlen(_TCHAR * wstr) { int l_idx = 0; while (((char*)wstr)[l_idx]!=0) l_idx+=2; return l_idx; } // Allocate char string and copy TCHAR->char->string // Don't forget to release the allocated memory!!! char * wstrdup(_TCHAR * wSrc) { int l_idx=0; int l_len = wstrlen(wSrc); char * l_nstr = (char*)malloc(l_len); if (l_nstr) { do { l_nstr[l_idx] = (char)wSrc[l_idx]; l_idx++; } while ((char)wSrc[l_idx]!=0); } nstr[l_idx] = 0; return l_nstr; }
