C/C++
Internals
Overview
This 3 day class is designed to build on existing
knowledge of the C/C++ product in the TPF
environment. It will provide programmers and
support staff with the knowledge to debug programs
and identify system errors. The class includes frequent
exercises to reinforce knowledge gained during the
lecture sessions.
Audience
TPF staff who require knowledge of the internals and
architecture of the C/C++ product in TPF.
Students should have an reasonable understanding of
TPF. A working knowledge of C Coding concepts
is desirable.
Student Numbers
The maximum recommended student to instructor
ratio is 12:1
Objectives
By the end of the course, the delegates will be
able, with the aid of course notes to:
-
List
the C/C++ register conventions.
-
Identify
Stack, Heap and Static storage.
-
Describe
compiler options and their impact on generated
object code.
-
Understand
various linkage mechanisms used in C/C++
programs.
-
Solve
dumps in DLMs and DLLs
