Your cache plug-in must exist in a shared library and have the following extern C function defined whos parameters are:
Logger | Pointer to the logger object that should be used with an instance of XrdSysError to direct messages to a log file. If Logger is null, you should use cerr to output messages. | |
Config | Pointer to the configuration file name from where you should get additional information. If Config is null, there is no configuration file is present. | |
Parms | Pointer to any parameters specified after the shared library path. If Parms is null, there are no parameters. | |
envP | Pointer to environmental information. The most relevant is whether or not gStream monitoring is enabled. XrdXrootdGStream *gStream = (XrddXrootdGStream *) envP->GetPtr("pfc.gStream*"); |
extern "C" { XrdOucCache *XrdOucGetCache(XrdSysLogger *Logger, // Where messages go const char *Config, // Config file used const char *Parms, // Optional parm string } XrdOucEnv *envP); // Optional environment
