One render function converts a getnamebyaddr request structure \(em -\fBlwres_gnbarequest_t\fR -\(em to the lightweight resolver's canonical format. It is complemented by a parse function that converts a packet in this canonical format to a getnamebyaddr request structure. Another render function converts the getnamebyaddr response structure \(em -\fBlwres_gnbaresponse_t\fR -to the canonical format. This is complemented by a parse function which converts a packet in canonical format to a getnamebyaddr response structure. -.PP -These structures are defined in -\fIlwres/lwres.h\fR. They are shown below. -.sp -.nf -#define LWRES_OPCODE_GETNAMEBYADDR 0x00010002U -typedef struct { - lwres_uint32_t flags; - lwres_addr_t addr; -} lwres_gnbarequest_t; -typedef struct { - lwres_uint32_t flags; - lwres_uint16_t naliases; - char *realname; - char **aliases; - lwres_uint16_t realnamelen; - lwres_uint16_t *aliaslen; - void *base; - size_t baselen; -} lwres_gnbaresponse_t; -.fi -.sp -.PP -\fBlwres_gnbarequest_render()\fR -uses resolver context -\fIctx\fR -to convert getnamebyaddr request structure -\fIreq\fR -to canonical format. The packet header structure -\fIpkt\fR -is initialised and transferred to buffer -\fIb\fR. The contents of -\fI*req\fR -are then appended to the buffer in canonical format. -\fBlwres_gnbaresponse_render()\fR -performs the same task, except it converts a getnamebyaddr response structure -\fBlwres_gnbaresponse_t\fR -to the lightweight resolver's canonical format. -.PP -\fBlwres_gnbarequest_parse()\fR -uses context -\fIctx\fR -to convert the contents of packet -\fIpkt\fR -to a -\fBlwres_gnbarequest_t\fR -structure. Buffer -\fIb\fR -provides space to be used for storing this structure. When the function succeeds, the resulting -\fBlwres_gnbarequest_t\fR -is made available through -\fI*structp\fR. -\fBlwres_gnbaresponse_parse()\fR -offers the same semantics as -\fBlwres_gnbarequest_parse()\fR -except it yields a -\fBlwres_gnbaresponse_t\fR -structure. -.PP -\fBlwres_gnbaresponse_free()\fR -and -\fBlwres_gnbarequest_free()\fR -release the memory in resolver context -\fIctx\fR -that was allocated to the -\fBlwres_gnbaresponse_t\fR -or -\fBlwres_gnbarequest_t\fR -structures referenced via -\fIstructp\fR. Any memory associated with ancillary buffers and strings for those structures is also discarded. -.SH "RETURN VALUES" -.PP -The getnamebyaddr opcode functions -\fBlwres_gnbarequest_render()\fR, -\fBlwres_gnbaresponse_render()\fR\fBlwres_gnbarequest_parse()\fR -and -\fBlwres_gnbaresponse_parse()\fR -all return -\fBLWRES_R_SUCCESS\fR -on success. They return -\fBLWRES_R_NOMEMORY\fR -if memory allocation fails. -\fBLWRES_R_UNEXPECTEDEND\fR -is returned if the available space in the buffer -\fIb\fR -is too small to accommodate the packet header or the -\fBlwres_gnbarequest_t\fR -and -\fBlwres_gnbaresponse_t\fR -structures. -\fBlwres_gnbarequest_parse()\fR -and -\fBlwres_gnbaresponse_parse()\fR -will return -\fBLWRES_R_UNEXPECTEDEND\fR -if the buffer is not empty after decoding the received packet. These functions will return -\fBLWRES_R_FAILURE\fR -if -pktflags -in the packet header structure -\fBlwres_lwpacket_t\fR -indicate that the packet is not a response to an earlier query. -.SH "SEE ALSO" -.PP -\fBlwres_packet\fR(3). |
