typedef struct _DICOMNETCALLBACKEXT

} DICOMNETCALLBACKEXT, * pDICOMNETCALLBACKEXT;

The DICOMNETCALLBACKEXT structure contains information concerning the non-communication related DICOM callback functions.

Member	Description
uStructSize	The size of the structure (use sizeof (DICOMNETCALLBACKEXT)).
pfnPrivateKeyPassword	Pointer to a PRIVATEKEYPASSWORD function.
pUserDataPrivateKeyPassword	A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the calling function.)
	Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
