Pass two pointer parameters to the r_debug_state() hook function, thus allowing a debugger or other trace tool to easily grab the addresses of the needed structures off the stack.
Pass two pointer parameters to the r_debug_state() hook

to easily grab the addresses of the needed structures
off the stack.

for comparison purposes.

A sample program will be committed showing how this can
be used.
