Int 2F Fn 111B  CU - Network Redirector - Findfirst                        [N]

   AX = 111Bh
   SS = DS = DOS DS
   [DTA] = uninitialized 21-byte findfirst search data (see INT 21/AH=4Eh)
   SDA first filename pointer -> fully-qualified search template
   SDA CDS pointer -> current directory structure for drive with file
   SDA search attribute = attribute mask for search

Return: CF set on error
       AX = DOS error code (see INT 21/AH=59h)
   CF clear if successful
       [DTA] = updated findfirst search data
           (bit 7 of first byte must be set)
       [DTA+15h] = standard directory entry for file

Note:  this function is called by the DOS 3.1+ kernel
