Hey guys,

I'm working on a C++ program that runs/processes data from a bash shell on Cygwin. I've written code to parse command line arguments like so:

Qt Code: 
  1. // in main(int argc, char *argv[])
  2. char    testFile[10][256];      // holds up to 10 testFile names of up to 256 char each
  3. uint16  testFileNUM = 0;
  4.  
  5.  
  6. //  call my parsing function:
  7. doArgs(argc, argv);
  8.  
  9.  
  10. //  afterward report the parameter info
  11. for(uint16 a=0; a<testFileNUM; a++)
  12.   printf("TestFile and NUM:    %s   %hd\n", testFile[a], testFileNUM);
  13.  
  14.  
  15. // snippet from command line parsing function
  16. void doArgs(int argc, char *argv[])
  17. {
  18.   char *a;
  19.   while(--argc > 0 && (*++argv)[0] == '-')
  20.   {
  21.     a = argv[0] + 1;
  22.     switch(*a)
  23.     {
  24.       case 't':
  25.         if(!strcasecmp(a, "test_file"))
  26.         {
  27.           sscanf(*++argv, "%s", &testFile[testFileNUM]);
  28.           testFileNUM++;
  29.           argc--;
  30.         }
  31.         else
  32.         {
  33.           printf("Unknown option:  %s\n", *argv);
  34.           usage();
  35.           exit(1);
  36.         }
  37.         break;
  38.       //  etc...  
  39.     }
  40.   }
  41. }

This has worked fine for me. If I type:

$> program -test_file text01.txt -test_file text02.txt -test_file text03.txt

I get the following expected report:

$> TestFile and NUM: text01.txt 3
$> TestFile and NUM: text02.txt 3
$> TestFile and NUM: text03.txt 3


This is what I want: after the file names have been read into the program, I can open them and do what I want.

However, now I've a situation such that, instead of specifying the input files specifically, I want to read them using a wildcard like so:

$> program -test_file text*.txt

But when I do so, I get the following report:

$> TestFile and NUM: text*.txt 1


This is useless to me (I think): I cannot keep track of and access the individual files. Can someone give me a suggestion here: how can I read the individual file names in my doArgs() function using the * wildcard?

Thanks!
