bw_trace_reset() – Perform a trace reset

Description

Perform a trace reset

If the trace file exists and is writable then we can attempt to unlink it. We precede the call to unlink with an @ to attempt to avoid getting warning messages. This file may not exist so we have two choices. 1. precede with an @, 2. test for it but if $file is not set then we should test Note: We shouldn't be doing this if we're not tracing the specific IP.

Usage

bw_trace_reset();

Parameters

Returns

void
