[von EinGutesExceptionBeispiel]

error=0; file=FileOpenMess("test.txt"); // generates default error message if(file==NULL) { error=-1; goto finalize; } status=FileWriteMess(file,"name=" + name); // generates default error message if(status) { error=-1; goto finalize; } status=FileWriteContent(file); if(status) { message(...); error=-1; goto finalize; } finalize: FileClose(file); // tolerant gegen file==NULL return error;

Aber, aber, es geht doch auch ohne 'goto':

error=-1; file=FileOpenMess("test.txt"); // generates default error message if(file==NULL) { error_a: } status=FileWriteMess(file,"name=" + name); // generates default error message if(status) { error_b: } status=FileWriteContent(file); if(status) { message(...); error_c: } error=0; comefrom error_a; comefrom error_b; comefrom error_c; FileClose(file); // tolerant gegen file==NULL return error;

;-) -- vgl

Wenn schon, denn schon:

 
  error=-1;
  file=FileOpenMess("test.txt"); // generates default error message
error_a:
  status=FileWriteMess(file,"name=" + name); // generates default error message
error_b:
  status=FileWriteContent(file);
error_c:
  error=0;
  if (file==NULL) comefrom error_a;
  if (status) comefrom error_b;
  comefrom error_message;
  FileClose(file); // tolerant gegen file==NULL
  return error;

  if (status) comefrom error_c;
  message(...);
error_message:
