ed - edit a file
|
|
|
|
This efun is only available if OLD_ED is defined.
|
|
|
|
void ed( string file, string exit_fn, int restricted );
|
|
|
|
void ed( string file, string write_fn, string exit_fn, int restricted );
|

|
This is a funny function. It will start a local editor on an optional
|
|
file. This editor is almost UNIX ed compatible. When in the editor
|
|
type 'h' for help.
|
|
|
|
The 'write_fn' function allows the mudlib to handle file locks and
|
|
administrative logging of files modified. When the editor writes to a
|
|
file, the driver will callback the 'write_fn' function twice. The first
|
|
time, the function is called before the
|
|
write takes place -- 'flag' will be 0. If the function returns 1,
|
|
the write will continue,
|
|
otherwise it will abort. The second time, the function is called
|
|
after the write has completed -- 'flag' will be non-zero.
|
|
This callback function should have the form:
|
|
|
|
int write_fn(string fname, int flag)
|
|
|
|
When the editor is exited, the driver will callback the 'exit_fn'
|
|
function. This function allows the mudlib to clean up. This
|
|
callback function has the form:
|
|
|
|
void exit_fn()
|
|
|
|
The optional 'restricted' flag limits the editor's
|
|
capabilities, such as inserting a file, and saving using an alternate
|
|
file name.
