Purpose

Trace -data is written to kernel side chunks. The kernel trace tool API can specify -which trace data should be made available for further processing by setting -filters.

-
Intended audience

This -document is intended for third party developers writing a trace tool using -the kernel trace tool component.

-
Required background

The -trace filters defined in EUser. The kernel trace tool component -in general.

-
Introduction

Setting -trace filters is a short task which is performed in combination with related -tasks as explained in Kernel -Trace Tool Tutorial.

Using Kernel -Trace tool to set trace filters

The following tasks will be covered -in this tutorial:

    -

  • Setting trace filters.

    • -
-
Basic procedure

The -high level steps to setting trace filters are shown here:

    -

  1. Set a primary filter -specifying a category of data and whether it is to be output or not.

    2. -

  2. Set a secondary filter -if necessary.

    3. -
-
Using the API

These -are the function calls required to

    -

  1. Call the SetFilter() function -of the RBTrace object. This function takes two arguments:

      -

    • An integer representing -the trace category taken from the enumeration BTrace::TCategories, -and

      • -

    • A boolean, True if the -trace category is to be output and False if it is not.

      • -
    2. -

  2. If you need a secondary -trace filter, call the SetFilter2() function of the RBTrace object.
