6769e6a99f - Moved PFS header from Apple2 directory to 6502 directory as we're going to have other PFS implementations.
- Completed declarations.

50be40768b Removed closing of stdin, stdout (and stderr on the Apple2). It was introduced in order to maximize the number of available file handles for the webserver. However none of the target machine DOSes allows to open a single file several times diminishing the intended effect very much. One the other hand not being able to "just printf() something" causes trouble over and again - i.e. hello-world seemingly not working...after all a typical case of german over-enigneering ;-) 2010-02-10 07:43:25 +00:00

daf29d0a87 Supply prototype even if there's no implementation (yet) to keep compiler happy. 2009-09-13 19:07:34 +00:00

852d2c0283 Introduced very lightweight pfs implementation based on Apple ProDOS.
ProDOS requires for each opened file a user-supplied page-aligned 1024 byte i/o buffer. This makes the generic POSIX file i/o library contained in the cc65 C-library quite heavyweight.

In contrast the lightweight pfs implementation uses the uIP packet buffer as ProDOS i/o buffer. Therefore:
- Only one file may be open at any time.
- That file may not be open while the uIP packet buffer is used by uIP. The open()/read()/close() sequence should be completed before Contiki event scheduling or inside handling a single Contiki event.
- The uIP packet buffer must be large enough to hold the ProDOS I/O buffer. Depending on the position of the uIP buffer in memory this means between 1024 and 1024 + 256 bytes. Therefore in an Ethernet environment setting the MTU_SIZE to at least 1266 is safe (So the default of 1500 is just fine).

8644822a34 Soe we're finally back at reducing the memory footprint be avoiding to pull in large C-library enitities. 2007-12-16 13:08:09 +00:00
