XrdOucgetGMap()

XrdOucGMap * XrdOucgetGMap

(

XrdOucGMapArgs

)

Obtain an instance of the XrdOucGMap object.

This extern "C" function is called when a shared library plug-in containing implementation of this class is loaded. It must exist in the shared library and must be thread-safe.

Parameters

eDest	-> The error object that must be used to print any errors or other messages (see XrdSysError.hh).
mapfn	-> Path to the grid map file to be used. This pointer may be null; the default path will be tested then.
parms	-> Argument string specified on the gridmap directive. It may be null or point to a null string if no parms exist.

Returns

Success: A pointer to an instance of the XrdOucGMap object. Failure: A null pointer which causes initialization to fail.

The GMap object is used frequently in the course of creating new physical connections. The algorithms used by this object must be efficient and speedy; otherwise system performance will be severely degraded. Declare compilation version.

Additionally, you should declare the xrootd version you used to compile your plug-in. While not currently required, it is highly recommended to avoid execution issues should the class definition change. Declare it as:

#include "XrdVersion.hh"
XrdVERSIONINFO(XrdOucgetGMap,<name>);

where <name> is a 1- to 15-character unquoted name identifying your plugin.
