These routines 81 deal with the creation of service handles. Once the handle is created, the 82 server can be invoked by calling \fBsvc_run()\fR. 83 .SS "Routines" 84 .sp 85 .LP 86 See \fBrpc\fR(3NSL) for the definition of the \fBSVCXPRT\fR data structure. 87 .sp 88 .ne 2 89 .na 90 \fB\fBsvc_control()\fR\fR 91 .ad 92 .RS 21n 93 A function to change or retrieve information about a service object. \fIreq\fR 94 indicates the type of operation and \fIinfo\fR is a pointer to the information. 95 The supported values of \fIreq\fR, their argument types, and what they do are: 96 .sp 97 .ne 2 98 .na 99 \fB\fBSVCGET_VERSQUIET\fR\fR 100 .ad 101 .RS 25n 102 If a request is received for a program number served by this server but the 103 version number is outside the range registered with the server, an 104 \fBRPC_PROGVERSMISMATCH\fR error will normally be returned. \fIinfo\fR should 105 be a pointer to an integer. Upon successful completion of the 106 \fBSVCGET_VERSQUIET\fR request, *\fIinfo\fR contains an integer which 107 describes the server's current behavior: \fB0\fR indicates normal server 108 behavior, that is, an \fBRPC_PROGVERSMISMATCH\fR error will be returned. 109 \fB1\fR indicates that the out of range request will be silently ignored. 110 .RE 111 112 .sp 113 .ne 2 114 .na 115 \fB\fBSVCSET_VERSQUIET\fR\fR 116 .ad 117 .RS 25n 118 If a request is received for a program number served by this server but the 119 version number is outside the range registered with the server, an 120 \fBRPC_PROGVERSMISMATCH\fR error will normally be returned. It is sometimes 121 desirable to change this behavior. \fIinfo\fR should be a pointer to an integer 122 which is either \fB0\fR, indicating normal server behavior and an 123 \fBRPC_PROGVERSMISMATCH\fR error will be returned, or \fB1\fR, indicating that 124 the out of range request should be silently ignored. 125 .RE 126 127 .sp 128 .ne 2 129 .na 130 \fB\fBSVCGET_XID\fR\fR 131 .ad 132 .RS 25n 133 Returns the transaction \fBID\fR of connection\(mioriented and connectionless 134 transport service calls. The transaction \fBID\fR assists in uniquely 135 identifying client requests for a given \fBRPC\fR version, program number, 136 procedure, and client. The transaction \fBID\fR is extracted from the service 137 transport handle \fIsvc\fR. \fIinfo\fR must be a pointer to an unsigned long. 138 Upon successful completion of the \fBSVCGET_XID\fR request, *\fIinfo\fR 139 contains the transaction \fBID\fR. Note that rendezvous and raw service 140 handles do not define a transaction \fBID\fR. Thus, if the service handle is 141 of rendezvous or raw type, and the request is of type \fBSVCGET_XID,\fR 142 \fBsvc_control()\fR will return \fBFALSE\fR. Note also that the transaction 143 \fBID\fR read by the server can be set by the client through the suboption 144 \fBCLSET_XID\fR in \fBclnt_control()\fR.

This handler is only useful for a connection oriented service handle. 157 .sp 158 \fI*info\fR contains the address of the error handler to attach, or \fINULL\fR 159 to detach a previously defined one. The error handler has two arguments. It has 160 a pointer to the erroneous service handle.

Typically, this descriptor is a connected file 275 descriptor for a connection-oriented transport. \fIsendsz\fR and \fIrecvsz\fR 276 indicate sizes for the send and receive buffers.
