|

*
|
||||
* The circular buffer implementation is as follows:
|
||||
* - buffer::{data[DATASIZE], dataoff, datalen};
|
||||
* - data storage is preallocated to a fixed capacity: DATASIZE;
|
||||
* - dataoff is used to track the data start (for read);
|
||||
* - datalen is the stored data's length;
|
||||
* - DATATAIL() macro is to track the data end position (for write);
|
||||
* - Both start and end positions may be wrapped around at the DATASIZE,
|
||||
* (& DATAMASK);
|
||||
* - DATAROOM() macro is used to determine the currently available
|
||||
* length of the __contiguous__ storage after the data end (from DATATAIL)
|
||||
* - write is allowed only into the remaining capacity, overwriting of the
|
||||
* the buffered but not consumed data is not allowed;
|
||||
* - once data has been consumed, the dataoff and datalen must be adjusted
|
||||
* accordingly; dataoff may wrap around (& DATAMASK);
|
||||
* - when DATAROOM() returns 0, the data must be consumed before any more
|
||||
* data could be buffered.
|
||||
*
|
||||
* NOTE: the DATAROOM() does not wrap around and yields the length
|
||||
* from DATATAIL() up to the DATASIZE position. So the returned length may
|
||||
* be shorter than the actual remaining capacity, that is there may be
|
||||
* more unoccupied space from the beginning of the buffer till dataoff.
|
||||
*
|
||||
* This is because the buffer's storage pointer at the write position is passed
|
||||
* directly to the IO receive call, so it's expected to be contiguous and can't
|
||||
* wrap around. Thus in such cases this may result in extra IO receive call in
|
||||
* order to first fill the residual length till DATASIZE, and then continue
|
||||
* filling from the start of the buffer.
|
||||
*
|
