CMediaType::operator = (Windows Embedded CE 6.0)

1/6/2010

The CMediaType variation of this operator is the copy constructor for a CMediaType object.

The AM_MEDIA_TYPE variation of this operator is the copy constructor for an AM_MEDIA_TYPE object.

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 CMediaType class inherits publicly from AM_MEDIA_TYPE, the compiler could generate the copy constructor for the AM_MEDIA_TYPE object 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 pbFormat member points to), which the compiler's copy constructor will not copy correctly.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later
