The opcode is intended to allow a client to determine if the server is operational or not. -.PP -There are four main functions for the no\-op opcode. One render function converts a no\-op request structure \(em -\fBlwres_nooprequest_t\fR -\(em to the lighweight resolver's canonical format. It is complemented by a parse function that converts a packet in this canonical format to a no\-op request structure. Another render function converts the no\-op response structure \(em -\fBlwres_noopresponse_t\fR -to the canonical format. This is complemented by a parse function which converts a packet in canonical format to a no\-op response structure. -.PP -These structures are defined in -\fIlwres/lwres.h\fR. They are shown below. -.PP -.RS 4 -.nf -#define LWRES_OPCODE_NOOP 0x00000000U -.fi -.RE -.sp -.PP -.RS 4 -.nf -typedef struct { - lwres_uint16_t datalength; - unsigned char *data; -} lwres_nooprequest_t; -.fi -.RE -.sp -.PP -.RS 4 -.nf -typedef struct { - lwres_uint16_t datalength; - unsigned char *data; -} lwres_noopresponse_t; -.fi -.RE -.sp -.PP -Although the structures have different types, they are identical. This is because the no\-op opcode simply echos whatever data was sent: the response is therefore identical to the request. -.PP -\fBlwres_nooprequest_render()\fR -uses resolver context -\fIctx\fR -to convert no\-op 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_noopresponse_render()\fR -performs the same task, except it converts a no\-op response structure -\fBlwres_noopresponse_t\fR -to the lightweight resolver's canonical format. -.PP -\fBlwres_nooprequest_parse()\fR -uses context -\fIctx\fR -to convert the contents of packet -\fIpkt\fR -to a -\fBlwres_nooprequest_t\fR -structure. Buffer -\fIb\fR -provides space to be used for storing this structure. When the function succeeds, the resulting -\fBlwres_nooprequest_t\fR -is made available through -\fI*structp\fR. -\fBlwres_noopresponse_parse()\fR -offers the same semantics as -\fBlwres_nooprequest_parse()\fR -except it yields a -\fBlwres_noopresponse_t\fR -structure. -.PP -\fBlwres_noopresponse_free()\fR -and -\fBlwres_nooprequest_free()\fR -release the memory in resolver context -\fIctx\fR -that was allocated to the -\fBlwres_noopresponse_t\fR -or -\fBlwres_nooprequest_t\fR -structures referenced via -\fIstructp\fR. -.SH "RETURN VALUES" -.PP -The no\-op opcode functions -\fBlwres_nooprequest_render()\fR, -\fBlwres_noopresponse_render()\fR -\fBlwres_nooprequest_parse()\fR -and -\fBlwres_noopresponse_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_nooprequest_t\fR -and -\fBlwres_noopresponse_t\fR -structures. -\fBlwres_nooprequest_parse()\fR -and -\fBlwres_noopresponse_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 -\fBpktflags\fR -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) -.SH "COPYRIGHT" -Copyright \(co 2004, 2005, 2007 Internet Systems Consortium, Inc.
