From f190ec6882706d30c606e62986512371925288a9 Mon Sep 17 00:00:00 2001 From: Med Ismail Bennani Date: Fri, 3 Mar 2023 19:30:56 -0800 Subject: [lldb/Plugins] Add memory writing capabilities to Scripted Process This patch adds memory writing capabilities to the Scripted Process plugin. This allows to user to get a target address and a memory buffer on the python scripted process implementation that the user can make processing on before performing the actual write. This will also be used to write trap instruction to a real process memory to set a breakpoint.
