C++ Entry Point Syntax

The following paragraphs describes the syntax for C++ entry points.

VCSAgStartup

void VCSAgStartup();

The entry point VCSAgStartup() must use the primitive VCSAgRegisterEPStruct() to register the other entry points with the VCS agent framework. (See "VCS Primitives.) Note that the name of the C++ function must be VCSAgStartup().

For example:

// This example shows the VCSAgStartup() entry point
// implementation,assuming that the monitor, online, and
// offline entry points are implemented in C++ and the respective
// function names are res_monitor, res_online, and res_offline.

#include "VCSAgApi.h"
void VCSAgStartup() {
   VCSAgV40EntryPointStruct ep;
    ep.open = NULL;
    ep.close = NULL;
    ep.monitor = res_monitor;
    ep.online = res_online;
    ep.offline = res_offline;
    ep.action = NULL;
    ep.info = NULL;
    ep.attr_changed = NULL;
    ep.clean = NULL;
    ep.shutdown = NULL;
    VCSAgRegisterEPStruct(V40, &ep);
}
VCSAgResState res_monitor(const char *res_name, void
           **attr_val, int *conf_level) {
...
}
unsigned int res_online(const char *res_name,
           void **attr_val) {
...
}
unsigned int res_offline(const char *res_name,
            void **attr_val) {
...
}
