Function            fname_match - compare filenames w/wildcards

  Syntax              int fname_match(char *fname1, char *fname2);

  Prototype in        filehk.h

  Remarks             compares filename fname1 to fname2 with wildcard
                      matching (*,?). Case is irrelevant.

  Return value        return a value

                           < 0  if fname1 is less than fname2
                           = 0  if fname1 is the same as fname2
                           > 0  if fname1 is greater than fname2

  Note                fname_match() compares strings just like DOS does
                      (or at least DOS 3.2, the one I work under.) Thus:

                           "STR*.*" = "str*.*"
                           "str.d*" = "StR.DZ"
                           "str" = "str.c"

                      Very little error checking is done. If an invalid
                      filename is passed (i.e. more than 12 characters
                      long) unpredictable results may occur.

  Example             #include <filehk.h>

                      main()
                      {
                           char a[12], b[12];
                           int cmp;

                           strcpy(a,"stringhk.c");
                           strcpy(b,"?TRI*");
                           printf("%s ",a);
                           if ((cmp = fname_match(a,b)) == 0)
                                printf("=");
                           else if (cmp < 0)
                                     printf("<");
                                else
                                     printf(">");
                           printf(" %s\n",b);
                      }

  Program output      stringhk.c = ?TRI*
