/** Return a shortened buffer sequence.
|
|
|
|
This function returns a new buffer sequence which adapts the
|
|
passed buffer sequence and efficiently presents a shorter subset
|
|
of the original list of buffers starting with the first byte of
|
|
the original sequence.
|
|
|
|
@param n The maximum number of bytes in the wrapped
|
|
sequence. If this is larger than the size of passed,
|
|
buffers, the resulting sequence will represent the
|
|
entire input sequence.
|
|
|
|
@param buffers The buffer sequence to adapt. A copy of
|
|
the sequence will be made, but ownership of the underlying
|
|
memory is not transferred.
