DESCRIPTION
These functions allow a process to load further code and
data into the currently executing image. A dynamically-
loadable file, called a module here, is a variant of the
a.out(6) executable format with some extra components. The
loader for the architecture (see 2l(1)) creates a module
file from component object file(s) when given the -u option.
A module contains text and data sections, an import table,
an export table, and relocation data. The import table
lists the symbols the module needs from the loading program;
the export table lists symbols the module provides when
loaded. A program that loads a module provides a table of
its own symbols to match the symbols in the module's import
table.
Last summer I did a kernel module driver but a better management scheme
was suggested and I ripped it out and started again. But never finished.
