[Dev-C++] Errorhandling

[Christian W. <Chr...@vo...>]

Hi list,


I try to write a little Dos-tool.
If I want to get the parameters and the user has no parameters specified I
get an exception.

I think the error comes if i call strlen() with an empty string...

How can i handle this error, has anyone an idea ????



----------------Schnipp---------------------
	  //Get commandline
             strcpy(szDatei, argv[1]);
	  for (nCount = 2; argc > nCount; ++nCount)
	  {
               strcat(szDatei, " \0");
               strcat(szDatei, argv[nCount]);
	  };

	  //Check Commandline
	  if (strlen(szDatei) <= 5) 
	  {
	    printf("Wrong parameter !");
	  };
-------------------Schnapp------------------


Thanx for help
