MFnPlugin

The following is a new version of the hello command which uses MFnPlugin to register itself instead of using the macros in MSimple.h.

#include <stdio.h> 
#include <maya/MString.h> 
#include <maya/MArgList.h> 
#include <maya/MFnPlugin.h> 
#include <maya/MPxCommand.h> 
#include <maya/MIOStream.h> 
class hello : public MPxCommand 
{ 
public: 
    MStatus        doIt( const MArgList& args ); 
    static void*   creator(); 
}; 
MStatus hello::doIt( const MArgList& args ) { 
    cout << “Hello ” << args.asString( 0 ).asChar() ) << endl; 
    return MS::kSuccess; 
} 
void* hello::creator() { 
    return new hello; 
} 
MStatus initializePlugin( MObject obj ) { 
    MFnPlugin plugin( obj, “Autodesk”, “1.0”, “Any” ); 
    plugin.registerCommand( “hello”, hello::creator ); 
    return MS::kSuccess; 
} 
MStatus uninitializePlugin( MObject obj ) { 
    MFnPlugin plugin( obj ); 
    plugin.deregisterCommand( “hello” ); 
    return MS::kSuccess; 
} 

Note! initializePlugin() and uninitializePlugin() must be present in all plug-ins. If both or either is absent the plug-in will not be loaded and the creator is necessary to allow Maya to create instances of the class. See the following for details.
