It is sometimes desirable to choose specific access points from the candidates that match the template. In order to do this, the XPANSLookup routine can be called to return a list of matches, so that specific class:name instances can then be fed to \fIXPAGet()\fR, \fIXPASet()\fR, etc. .PP .Vb 4 \& The first argument is an optional XPA struct. If non\-NULL, the \&existing name server connection associated with the specified xpa is \&used to query the xpans name server for matching templates. Otherwise, \&a new (temporary) connection is established with the name server. .Ve .PP The second argument to XPANSLookup is the class:name template to match. .PP The third argument for \fIXPANSLookup()\fR is the type of access and can be any combination of: .PP .Vb 5 \& type explanation \& \-\-\-\-\-\- \-\-\-\-\-\-\-\-\-\-\- \& g xpaget calls can be made on this access point \& s xpaset calls can be made on this access point \& i xpainfo calls can be made on this access point .Ve .PP The call typically specifies only one of these at a time. .PP The final arguments are pointers to arrays that will be filled in and returned by the name server. The name server will allocate and return arrays filled with the classes, names, and methods of all \s-1XPA\s0 access points that match the template and have the specified type. Also returned are info strings, which generally are used internally by the client routines. These can be ignored (but the strings must be freed). The function returns the number of matches. The returned value can be used to loop through the matches: .PP \&\fBExample:\fR .PP .Vb 1 \& #include \& \& char **classes; \& char **names; \& char **methods; \& char **infos; \& int i, n; \& n = XPANSLookup(NULL, "foo*", "g", &classes, &names, &methods, &infos); \& for(i=0; i 0 ){ \& free(classes); \& free(names); \& free(methods); \& free(infos); \& } .Ve .PP The specified template also can be a host:port specification, for example: .PP .Vb 1 \& myhost:12345 .Ve .PP In this case, no connection is made to the name server. Instead, the call will return one entry such that the ip array contains the ip for the specified host and the port array contains the port. The class and name entries are set to the character \*(L"?\*(R", since the class and name of the access point are not known. .SH "SEE ALSO" .IX Header "SEE ALSO" See xpa(n) for a list of \s-1XPA\s0 help pages
