IffOffset()

template<class DataType >

DataType* Murl::Util::IffChunk::IffOffset ( UInt32  byteOffset ) const

inline

Get a typed pointer from an offset relative to the chunk.

Returns the address of the chunk + offset + sizeof(IffChunk).

Parameters

byteOffset

The byte offset.

Returns

The typed pointer or null if the offset is greater than the chunk size.

SetFourCC()

void Murl::Util::IffChunk::SetFourCC ( UInt32  fourCC )

inline

Set the chunk identifier.

This method takes care of the system's byte ordering.

Parameters

fourCC

The FourCC chunk identifier.

References Murl::Util::IffFourCC(), and mFourCC.

GetFourCC()

UInt32 Murl::Util::IffChunk::GetFourCC ( ) const

inline

Get the chunk identifier.

This method takes care of the system's byte ordering.

Returns

The FourCC chunk identifier.

References Murl::Util::IffFourCC(), and mFourCC.

SetChunkSize()

void Murl::Util::IffChunk::SetChunkSize ( UInt32  size )

inline

Set the chunk size.

This method takes care of the iff size format.

Parameters

size	The byte size of the chunk.

References mSize.

GetChunkSize()

UInt32 Murl::Util::IffChunk::GetChunkSize ( ) const

inline

Get the chunk size.

This method takes care of the iff size format.

Returns

The byte size of the chunk.

References mSize.

GetRawSize()

UInt32 Murl::Util::IffChunk::GetRawSize ( ) const

inline

Get the chunk size minus sizeof(IffChunk).

Returns

The byte size of the chunk minus sizeof(IffChunk).

References mSize.
