Searching memory (debugging with gdb)if the value size is not specified, it is taken from the value’s type in the current language Using the gdb python api to look into processes and read memory and display it in a helpful hex/text view, something which is otherwise challenging to achieve in gdb. This is useful when one wants to specify the search pattern as a mixture of types

A library for gdb (with python support), that adds useful functions to the standard 'gdb' library Creating conveniance variables in gdb
Gdb represents types from the inferior using the class gdb.type Gdb.lookup_type (name [, block]) this function looks up a type by its name, which must be a string If block is given, then name is looked up in that scope Otherwise, it is searched for globally.
You can get quick online help for gdb ’s python api by issuing the command python help (gdb) 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).
