RTLABEL_ID2NAME(9) FreeBSD Kernel Developer's Manual RTLABEL_ID2NAME(9) NAME rtlabel_id2name, rtlabel_id2sa, rtlabel_name2id, rtlabel_unref - manipulate route labels SYNOPSIS #include <sys/types.h> #include <sys/socket.h> #include <net/route.h> const char * rtlabel_id2name(u_int16_t id); struct sockaddr * rtlabel_id2sa(u_int16_t labelid, struct sockaddr_rtlabel *sa_rl); u_int16_t rtlabel_name2id(char *name); void rtlabel_unref(u_int16_t id); DESCRIPTION Route labels are arbitrary data appended to route entries and can be acted upon by pf(4). rtlabel_name2id(char *name) Return numerical ID of the route label named name, creating the label if it does not already exist. rtlabel_id2name(u_int16_t id) Return the string name of the route label with ID id. rtlabel_id2sa(u_int16_t labelid, struct sockaddr_rtlabel *sa_rl) Populate sa_rl with the data from the route label specified by labelid. rtlabel_unref(u_int16_t id) Remove a reference to the route label with ID id, freeing the label if the reference count drops to 0. CONTEXT rtlabel_id2name(), rtlabel_id2sa(), rtlabel_name2id(), and rtlabel_unref() can be called during autoconf, from process context, or from interrupt context. RETURN VALUES rtlabel_name2id() returns 0 if it was unable to create a route label. SEE ALSO route(4), route(9) FreeBSD 14.1-RELEASE-p8 October 15, 2014 FreeBSD 14.1-RELEASE-p8
