 This pair of routines will do a wildcard search
 you must call dfirst() once to supply the search pattern
 and get back the first file that matches that pattern.
 then, call dnext() to get the next file in the list.
 both dfirst() and dnext() return zero if a file has been found,
  non-zero otherwise.
 The calling parameters are as follows:
 dfirst(pattern,attr,file_name,file_date,file_time,file_size);
 dnext(file_name,file_date,file_time,file_size);
     Where:
 char *pattern;  (wild card pattern. eg. "*.c" )
 int   attr;  (the file attribute qualifier )
 char *file_name; (output: the name of found file (13 bytes min.) )
 int  *file_date; (output: the file's date (directory format) )
 int  *file_time; (output: the file's time )
 long *file_size; (output: the file's size in bytes )
