Remarks Returns a pointer to the internal character buffer for the CString object, truncating or growing its length if necessary to exactly match the length specified in <nNewLength>. The returned pointer to char is not const and thus allows direct modification of CString contents. If you use the pointer returned by GetBuffer to change the string contents, you must call ReleaseBuffer before using any other CString member functions. The address returned by GetBuffer is invalid after the call to ReleaseBuffer or any other CString operation. The buffer memory will be freed automatically when the CString object is destroyed. NOTE: If you keep track of the string length yourself, you need not append the terminating null byte. You must, however, specify the final string length when you release the buffer with ReleaseBuffer, or you can pass -1 for the length and ReleaseBuffer will perform a strlen on the buffer to determine its length. Return Value A char pointer to the object's (usually null-terminated) ASCII character buffer. See Also ◄CString::GetBuffer►, ◄CString::ReleaseBuffer► -♦-
