privatepure virtual

Given a buffer, fill the buffer with at most size bytes.

Parameters

buf	The buffer to be filled.
size	The maximum number of bytes to be read.

Returns

The number of bytes that were read. Should return zero at end of file. Should return a negative value in the case of error.

Implemented in TRawEventPipeSource, TRawEventGZipSource, TRawEventFileSource, and TRawEventOnlineFileSource.
