| Ausführliche Beschreibung | The Virtual Ring Buffer (VRB) is an implementation of a character
FIFO ring buffer. A ring buffer is a special memory area, because
writing beyond the end of it actually results in a write at the
beginning. Such a construct comes very handy in applications where
one end of a communications channel is required to produce or consume
data at a constant rate, but the other end cannot gurantee this. This
is a common situation in multimedia applications or Voice-over-IP
solutions, for example.
.
VRB provides direct access to the buffer so the calling program can
construct output data in place, or parse input data in place, without
the extra step of copying data to or from a calling program provided
buffer area, thus provides a highly efficient ring buffer
implementation.
