DESCRIPTION
|
|
This module provides the C++ style constructor mechanism used by various
|
|
components to initialize themselves automatically.
|
|
|
|
The _Ctors() routine is called from the nanokernel's _Cstart() routine after
|
|
hardware initialization has completed.
|
|
|
|
Although ctors are traditionally a C++ feature, normal C code can use them too
|
|
through the appropriate use of GCC's constructor attribute.
|
|
No destructor support (dtors) is provided.
