SYNOPSIS
string valid_write(string path, string uid, string func, object ob)
DESCRIPTION
This function is called to check if the object ob with the
user-id uid has write permissions to the file given by path
for the operation named by func. It should return 0 if
permission is denied, or the normalized path if permission is
granted. You can also return 1 to indicate that the path can
be used unchanged.
The returned pathname must not contain ``..'', a leading /
will be stripped by the interpreter.
Func denotes the efun call or other operation that caused
valid_write() to be called:
copy_file (for the target file or directory name)
rename_from (efun rename(), for the original name)
rename_to (efun rename(), for the new name)
ed_start (whenever the builtin ed tries to write to a file),
mkdir,
objdump
opcdump
remove_file (efun rm()),
rmdir,
save_object,
write_bytes,
write_file.
For save_object(), the <path> passed is the filename as given
in the efun call. If for this efun a filename ending in ".c" is
returned, the ".c" will be stripped from the filename.
This function is called in compat mode as well. If
you need to be compatible with the old 2.4.5-mudlib, redirect
these calls to the valid_read/valid_write in the user
object.
HISTORY
LDMud 3.2.8 adds operation "copy_file", and replaces "do_rename"
by "rename_from" and "rename_to".
