;; 2008-08-06 (mike.dld) ;;
|
|
;; changes: ;;
|
|
;; - split private procs into libio_p.asm, added comments ;;
|
|
;; 2007-12-10 (mike.dld) ;;
|
|
;; changes: ;;
|
|
;; - almost fully incompatible with previous version since return values were changed. ;;
|
|
;; now they are more C-like ;;
|
|
;; notes: ;;
|
|
;; - `file.err` is not yet available ;;
|
|
;; 2007-09-26 (mike.dld) ;;
|
|
;; changes: ;;
|
|
;; - modified `file.size` a bit (according to changes in FileInfo struct) ;;
|
|
;; - added `file.find_first`, `file.find_next`, `file.find_close` ;;
|
|
;; notes: ;;
|
|
;; - `file.aux.match_wildcard` is exported only for testing purposes, don't ;;
|
|
;; use it since it may be removed or renamed in next versions ;;
