RUNTIME_CLASS(class_name)

Parameters

class_name

The actual name of the class (not enclosed in quotation marks).

Remarks

Use this macro to get the run-time class structure from the name of a C++ class.

RUNTIME_CLASS returns a pointer to a CRuntimeClass structure for the class specified by class_name. Only CObject-derived classes declared with DECLARE_DYNAMIC, DECLARE_DYNCREATE, or DECLARE_SERIAL will return pointers to a CRuntimeClass structure.

For more information, see in Visual C++ Programmer’s Guide.

Example

// example for RUNTIME_CLASS
CRuntimeClass* prt = RUNTIME_CLASS( CAge );
ASSERT( lstrcmp( prt->m_lpszClassName, "CAge" )  == 0 );
