Buffer Information Structure

The buffer information structure is provided for your convenience in keeping track of where you last left off in an OTBuffer structure. Because the no-copy receive buffer structure (OTBuffer) is read-only, you may need to copy the data in sections as you progress through the no-copy receive buffer.

The buffer information structure is defined by the OTBufferInfo data type.

   struct OTBufferInfo
{
   OTBuffer*fBuffer;
   size_t   fOffset;
   UInt8    fPad;
};

typedef struct OTBufferInfo OTBufferInfo;

Field Description

fBuffer

A pointer to the no-copy receive buffer.

fOffset

An offset indicating how much of the buffer to read.

fPad

Reserved.
