The CMediaTypevariation of this operator is the copy constructor for a CMediaTypeobject.

The AM_MEDIA_TYPEvariation of this operator is the copy constructor for an AM_MEDIA_TYPEobject.

Syntax 

CMediaType& operator=(
  const CMediaType& 
rt 
);
CMediaType& operator=(
  const AM_MEDIA_TYPE& 
mrt 
);

Parameters

rt

Object to copy during the assignment operation.

mrt

Object to copy during the assignment operation.

Return Value

Returns a reference to this object after the operation.

Remarks

Because the CMediaTypeclass inherits publicly from AM_MEDIA_TYPE, the compiler could generate the copy constructor for the AM_MEDIA_TYPEobject itself.

However, this could introduce some memory conflicts and leaks in the process because the structure contains a dynamically allocated block (which the AM_MEDIA_TYPE  pbFormatmember points to), which the compiler's copy constructor will not copy correctly.
