PvRawData
Raw data interface to a PvBuffer.
Definition: PvRawData.h:25

PvRawData::Alloc
virtual PvResult Alloc(uint64_t aPayloadLength, uint32_t aMaximumChunkLength=0)=0
Allocates memory for this PvRawData.

PvRawData::Detach
virtual uint8_t * Detach()=0
Releases an attached memory buffer.

PvRawData::GetPayloadLength
virtual uint64_t GetPayloadLength() const =0
Get the payload length specified in the leader information of this block.

PvRawData::Free
virtual void Free()=0
Frees (de-allocates) the buffer's internal memory.

PvRawData::Attach
virtual PvResult Attach(void *aRawBuffer, uint64_t aPayloadLength, uint32_t aMaximumChunkLength=0)=0
Attach this PvRawData to an external memory buffer.

PvResult
Result information.
