GLOBAL FUNCTION

|
|
|
coff_solib_add -- add a shared library files to the symtab list. We

examine the `.lib' section of the exec file and determine the names of

the shared libraries.

This function is responsible for discovering those names and

addresses, and saving sufficient information about them to allow

their symbols to be read at a later time.

SYNOPSIS

DESCRIPTION
|
|
|
|
When gdb starts up the inferior, the kernel maps in the shared
|
|
libraries. We get here with the target stopped at it's first
|
|
instruction, and the libraries already mapped. At this point, this
|
|
function gets called via expansion of the macro
|
|
SOLIB_CREATE_INFERIOR_HOOK.
