Revision:	1.2
Committed:	1999-10-20T17:23:56Z (24 years, 8 months ago) by cebix
Branch:	MAIN
CVS Tags:	snapshot-21101999
Changes since 1.1:	+3 -1 lines
Log Message:	- fixed bugs in extfs.cpp: - root's parent now has an FSItem, so finding the volume by name with parent dirID 1 now works - fs_get_file_info() and fs_get_cat_info() handle all negative values of dir_index correctly - fs_set_fpos() handles fsFromLEOF positioning mode - replaced "%#s" format codes in debug output - fixed some file extensions in extfs_unix.cpp - "speaker" means "main volume", as before
