ed(3) LPC Library Functions ed(3) NAME ed() - edit a file SYNOPSIS void ed( string file, string exit_fn, int restricted ); void ed( string file, string write_fn, string exit_fn, int restricted ); DESCRIPTION This efun is only available if __OLD_ED__ is defined. 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 TRUE, the write will continue, other- wise 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 capabili- ties, such as inserting a file, and saving using an alter- nate file name.
