TBTraceBuffer Class Reference

class TBTraceBuffer

Member Functions Documentation

Adjust trace data size so it represents a whole number of trace records.

TUint aTail	The buffer offset where the available trace data is located.
TInt aSize	The size of data at aTail. Must be >= KMaxBTraceRecordSize.

Copy data out of the main trace buffer into the 'copy buffer'. This may fail if the data is overwritten before it hase been successfully copied.

Post-condition: iBuffer.iTail has been updated to point to the trace record following those copied.

TUint aData	The buffer offset where the available trace data is located.
TUint aTail	The value which iTail is expected to have if no more overwrites have occurred
TInt aSize	The size of data at aTail

Find out how much data is available.

TUint & aData	Set to the buffer offset where the available trace data is located.
TUint & aTail	Set to the the original value of the iTail pointer
