Addr in the api needs to be an integer, for example If you want to find the memory at the address of a variable or expression like you can with the gdb x command, then we can use gdb.parse_and_eval() function which will return a gdb.value object which has an address property. For example, i know an address like '0x7f0fdd25d7d0' and it represents a python object with known python class type Is there anyway to get the value of the fields of the object? This python script adds a new commmand findmap, which parses the output of info proc mappings and finds the origin file plus offset which is mapped at the given address This script is known to work with gdb 14.2 + python 3.12.3.
The default for addr is usually just after the last address examined—but several other commands also set the default address Info breakpoints (to the address of the last breakpoint listed), info line (to the starting address of a line), and print (if you use it to display a value from memory). In this gdb tutorial, greg law explores a process's memory maps using info proc mappings and explains how to search memory for a string with the gdb command find. Introduction in the previous post we explored using find in various scenarios In this post we will streamline using find for some memory regions like.rodata,.text and.data We will use gdb view of the memory and turn it into some handy to use convenience variables, all using python and gdb python api.
Functions and methods which have two or more optional arguments allow them to be specified using keyword syntax This allows passing some optional arguments while skipping others Gdb.some_function('foo', bar = 1, baz = 2).
