Hi,
I am trying program using Lldb Python API to get an output exactly same
when I run this command "image lookup --address 0x0000000405a6 --verbose".
But when I print return value
of GetSymbolContext(lldb.eSymbolContextEverything), it doesnt contain the
decoding of local variables which the above commands can print out local
variables.
I have attached a simple script.py that I have developed. It is not
possible to print out local variables using the APIs or I am missing
something out?
I am looking forward to hear from you soon.
Thanks,
kmn
