See \fBrpcbind\fR(1M). 61 .SS "Routines" 62 .ne 2 63 .na 64 \fB\fBrpcb_getmaps()\fR\fR 65 .ad 66 .RS 18n 67 An interface to the \fBrpcbind\fR service, which returns a list of the current 68 \fBRPC\fR program-to-address mappings on \fIhost\fR. It uses the transport 69 specified through \fInetconf\fR to contact the remote \fBrpcbind\fR service on 70 \fIhost\fR. This routine will return \fBNULL,\fR if the remote \fBrpcbind\fR 71 could not be contacted. 72 .RE 73 74 .sp 75 .ne 2 76 .na 77 \fB\fBrpcb_getaddr()\fR\fR 78 .ad 79 .RS 18n 80 An interface to the \fBrpcbind\fR service, which finds the address of the 81 service on \fIhost\fR that is registered with program number \fIprognum\fR, 82 version \fIversnum\fR, and speaks the transport protocol associated with 83 \fInetconf\fR. The address found is returned in \fIsvcaddr\fR. \fIsvcaddr\fR 84 should be preallocated. This routine returns \fBTRUE\fR if it succeeds. A 85 return value of \fBFALSE\fR means that the mapping does not exist or that the 86 \fBRPC\fR system failed to contact the remote \fBrpcbind\fR service. In the 87 latter case, the global variable \fBrpc_createerr\fR contains the \fBRPC\fR 88 status. See \fBrpc_clnt_create\fR(3NSL). 89 .RE 90 91 .sp 92 .ne 2 93 .na 94 \fB\fBrpcb_gettime()\fR\fR 95 .ad 96 .RS 18n 97 This routine returns the time on \fIhost\fR in \fItimep\fR. If \fIhost\fR is 98 \fINULL\fR, \fBrpcb_gettime()\fR returns the time on its own machine. This 99 routine returns \fBTRUE\fR if it succeeds, \fBFALSE\fR if it fails. 100 \fBrpcb_gettime()\fR can be used to synchronize the time between the client and 101 the remote server. This routine is particularly useful for secure RPC. 102 .RE 103 104 .sp 105 .ne 2 106 .na 107 \fB\fBrpcb_rmtcall()\fR\fR 108 .ad 109 .RS 18n 110 An interface to the \fBrpcbind\fR service, which instructs \fBrpcbind\fR on 111 \fIhost\fR to make an \fBRPC\fR call on your behalf to a procedure on that 112 host. The \fBnetconfig\fR structure should correspond to a connectionless 113 transport. The parameter \fB*\fR\fIsvcaddr\fR will be modified to the server's 114 address if the procedure succeeds. See \fBrpc_call()\fR and \fBclnt_call()\fR 115 in \fBrpc_clnt_calls\fR(3NSL) for the definitions of other parameters. 116 .sp 117 This procedure should normally be used for a "ping" and nothing else. This 118 routine allows programs to do lookup and call, all in one step. 119 .sp 120 Note: Even if the server is not running \fBrpcbind\fR does not return any error 121 messages to the caller. In such a case, the caller times out. 122 .sp 123 Note: \fBrpcb_rmtcall()\fR is only available for connectionless transports. 124 .RE 125 126 .sp 127 .ne 2 128 .na 129 \fB\fBrpcb_set()\fR\fR 130 .ad 131 .RS 18n 132 An interface to the \fBrpcbind\fR service, which establishes a mapping between 133 the triple [\fIprognum\fR, \fIversnum\fR, \fInetconf\fR->\fInc_netid]\fR and 134 \fIsvcaddr\fR on the machine's \fBrpcbind\fR service. The value of 135 \fInc_netid\fR must correspond to a network identifier that is defined by the 136 netconfig database. This routine returns \fBTRUE\fR if it succeeds, \fBFALSE\fR 137 otherwise. See also \fBsvc_reg()\fR in \fBrpc_svc_reg\fR(3NSL). If there 138 already exists such an entry with \fBrpcbind\fR, \fBrpcb_set()\fR will fail. 139 .RE 140 141 .sp 142 .ne 2 143 .na 144 \fB\fBrpcb_unset()\fR\fR 145 .ad 146 .RS 18n 147 An interface to the \fBrpcbind\fR service, which destroys the mapping between 148 the triple [\fIprognum\fR, \fIversnum\fR, \fInetconf\fR->\fInc_netid]\fR and 149 the address on the machine's \fBrpcbind\fR service. If \fInetconf\fR is 150 \fINULL\fR, \fBrpcb_unset()\fR destroys all mapping between the triple 151 [\fIprognum\fR, \fIversnum\fR, \fIall-transports\fR] and the addresses on the 152 machine's \fBrpcbind\fR service. This routine returns \fBTRUE\fR if it 153 succeeds, \fBFALSE\fR otherwise. Only the owner of the service or the 154 super-user can destroy the mapping.
