Int 21 Fn 714E  - Windows95 - Long Filename - Find First Matching File     [D]

   AX = 714Eh
   CL = allowable-attributes mask (see #1107 at AX=4301h)
         (bits 0 and 5 ignored)
   CH = required-attributes mask (see #1107)
   SI = date/time format (see #1467)
   DS:DX -> ASCIZ filespec (both "*" and "*.*" match any filename)
   ES:DI -> FindData record (see #1468)

Return: CF clear if successful
       AX = filefind handle (needed to continue search)
       CX = Unicode conversion flags (see #1469)
   CF set on error
       AX = error code
       7100h if function not supported

Notes: this function is only available when IFSMgr is running, not under bare
     MS-DOS 7
   the application should close the filefind handle with AX=71A1h as soon
     as it has completed its search
   for compatibility with DOS versions prior to v7.00, the carry flag
     should be set on call to ensure that it is set on exit
