Detailed Description
RTEMS Module Loading Debugger Interface.
Inspection of run-time linkers in NetBSD and Android show a common type of structure that is used to interface to GDB. The NetBSD definition of this interface is being used and is defined in <link.h>. It defines a protocol that is used by GDB to inspect the state of dynamic libraries. I have not checked GDB code at when writing this comment but I suspect GDB sets a break point on the r_brk field of _rtld_debug and it has code that detects this break point being hit. When this happens it reads the state and performs the operation based on the r_state field.

◆ _rtld_debug_state()
| void _rtld_debug_state | ( | void | ) |
Debugger break function.
Call when debugging to have it read the _rtld_debug variable.
