Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The packet passed to Subfunction 01h consists of five bytes. The
     first byte contains the level, which should be 00h for MS-DOS
     versions 2.0 and 3.0. The following four bytes contain the
     segment:offset of an ASCIIZ path name, which may not include
     wildcard characters. If the specified file exists, it is added to
     the print queue.
 
     The * and ? wildcard characters may be included in a path name
     passed to Subfunction 02h, making it possible to delete multiple
     files from the print queue with one call.
 
     The address returned by Subfunction 04h points to a list of
     64-byte entries, each containing an ASCIIZ path name. The first
     pathname in the list is the file currently being printed. The last
     entry in the list is a null string (a single 00h byte).
