Masking Issue in RL-ARM ffind Function

Hi there,

I'm using RL-FlashFS library and I want to get the list of text files with .txt extension.

So I use ffind http://www.keil.com/support/man/docs/rlarm/rlarm_ffind.htm function with "R:*.txt" parameter as follow:

  FINFO info;

  info.fileID = 0;                             /* info.fileID must be set to 0 */

  while (ffind ("R:*.TXT", &info) == 0)  {       /* find whatever is in drive "R0:" */
    printf ("\n%-32s %5d bytes, ID: %04d",
            info.name,
            info.size,
            info.fileID);
  }
  if (info.fileID == 0)  {
    printf ("\nNo files...");
  }

But it returns list of whole files including non-txt files.

I found that this problem occurs when using wild char in the beginning of mask, eg. "*something".
But there is no problem when using "something*".

Any ideas?
