Returns a pointer to the end of a null terminated string.
StrEnd returns a pointer to the null character at the end of Str.
C++ Examples:
/* The following example uses an edit control, a label, and a button on a form. When the button is clicked, the edit control’s text is copied into a buffer. Then the buffer is displayed backwards in the label. */ #include <memory> //for STL auto_ptr class void __fastcall TForm1::Button1Click(TObject *Sender) { std::auto_ptr<char> pszEditText(new char[Edit1->Text.Length()+1]); char *psz; StrCopy(pszEditText.get(), Edit1->Text.t_str()); psz = StrEnd(pszEditText.get()); Label1->Caption = ""; while (psz >= &pszEditText.get()[0]) { psz--; Label1->Caption = Label1->Caption + *psz; } }
Delphi Examples:
{ The following example uses an edit control, a label, and a button on a form. When the button is clicked, the edit control’s text is copied into a buffer. Then the buffer is displayed backwards in the label. } procedure TForm1.Button1Click(Sender: TObject); var TextBuffer: PChar; Ptr: PChar; begin GetMem(TextBuffer, Length(Edit1.Text)+1); StrCopy(TextBuffer, PChar(Edit1.Text)); Ptr := StrEnd(TextBuffer); Label1.Caption := ''; while Ptr > TextBuffer do begin Dec(Ptr); Label1.Caption := Label1.Caption + Ptr^; end; FreeMem(TextBuffer); end;
