[Libsysio-commit] HEAD: libsysio/dev/stdfd stdfd.c

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio/dev/stdfd
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv25715/dev/stdfd

Modified Files:
	stdfd.c 
Log Message:


From Henry Pierce at Cray; A chdir() to a directory without `x' permission
should not succeed but does.

This required that inodes now carry the full attributes -- Not just the
mode bits. That's a bug change.

Driver writers;
	1) _sysio_i_new is altered. It needs the full intnl_stat structure
	now.
	2) Your lookup function should refresh the inode attributes.
	3) We don't keep an inode dirty bit. Hopefully, you've been
	pushing changes at the time of the operation instead of waiting
	until the inode was flushed or somesuch. Maybe you keep an internal
	dirty bit?
