.\"edit a file .TH ed 3 "5 Sep 1994" MudOS "LPC Library Functions" .SH NAME ed() - edit a file .SH SYNOPSIS .nf void ed( string file, string exit_fn, int restricted ); void ed( string file, string write_fn, string exit_fn, int restricted ); .SH 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, 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: .IP int write_fn(string fname, int flag) .PP 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: .IP void exit_fn() .PP The optional <restricted> flag limits the editor's capabilities, such as inserting a file, and saving using an alternate file name. .SH SEE ALSO regexp(3), valid_read(4), valid_write(4), get_save_file_name(4)
