Re: Implementing a file counter (like "ls | wc")

[Luciano Moreira - igLnx <lucianolnx@ig.com.br>]

-------------- THE CODE HAVE THIS STRUCTURE:
while ((pFile=readdir(pDir))!=NULL) {
      sprintf(szBuf, "%s/%s", pPath, pFile->d_name);
      stat(szBuf, &statFile);
      if (S_ISDIR(statFile.st_mode))  /// LOOK THAT: We don't use 
recursive searching, we count only files at current directory excluding 
others directories.
         continue;

      /* Filtering */
      if (nNeedFilter) {
          //// I DONT HAVE THE CODE OF FILTERING NOW
          //// BUT I CAN SEND IT LATER IF NECESSARY
         }

   }
-------------- CODE FINISH HERE

Does have another mechanism to filter without using of strcmp() / 
memcmp() ? How if we dont know the size of extension (.c, .cpp, .teste, 
.longextension, and so on). ?
