834 DEFUN ("delete-process", Fdelete_process, Sdelete_process, 1, 1, 0,
835 doc: /* Delete PROCESS: kill it and forget about it immediately.
836 PROCESS may be a process, a buffer, the name of a process or buffer, or
837 nil, indicating the current buffer's process. */)
838 (register Lisp_Object process)
839 {
840 register struct Lisp_Process *p;
841
842 process = get_process (process);
843 p = XPROCESS (process);
844
845 #ifdef HAVE_GETADDRINFO_A
846 if (p->dns_request)
847 {
848 gai_cancel (p->dns_request);
849 free_dns_request (process);
850 }
851 #endif
The man page says gai_cancel does not cancel the request if it is
currently being processed. So I suspect it is unsafe to free struct
gaicb by calling free_dns_request if the request was not canceled
actually.
