.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module implements named buffers to be used for logging purposes.
Each buffer is of a concrete size (definable by the developer) with a
max message length of 2KB.  Each message is stored with a timestamp.  Once
the buffer hits the maximun number of entries it begins deleting the oldest
messages as the new messages come in.
.PP
Buffers are created automatically on the fly, and messages trimmed
before being stored.
.PP
With the exception of the \fBdump\fR function this module is not meant to be
used directly.  \fBParanoid::Log\fR should be your exclusive interface for
logging.
.PP
When enabling a buffer facility with \fBParanoid::Log\fR you can add one integral
argument to the call.  That number defines the size of the log buffer in
terms of number of entries allowed.
.PP
\&\fB\s-1NOTE:\s0\fR Buffers are maintained within process memory.  If you fork
a process from a parent with a log buffer each copy will maintain its own
entries.

.Ve
.PP
This dumps all current entries in the named buffer.  Each entry is an
array reference to a two-element array.  The first element is the timestamp
of the message (in \s-1UNIX\s0 epoch seconds), the second the actual message
itself.
