udmp-parser: A Windows user minidump C++ parser library.
This is a cross-platform (Windows / Linux / OSX / x86 / x64) C++ library that parses Windows user minidump dumps (.dump /m and not .dump /f in WinDbg usermode).
The library supports Intel 32-bit / 64-bit dumps and provides read access to things like:
- The thread list and their context records,
- The virtual memory,
- The loaded modules.
Compiled binaries are available in the releases section.
Parser
The parser application is a small utility to show-case how to use the library and demonstrate its features. You can use it to dump memory, list the loaded modules, dump thread contexts, dump a memory map various, etc.
Here are the options supported:
parser.exe [-a] [-mods] [-mem] [-t [<TID>|main] [-h] [-dump <addr>] <dump path>
Examples:
Show all:
parser.exe -a user.dmp
Show loaded modules:
parser.exe -mods user.dmp
Show memory map:
parser.exe -mem user.dmp
Show all threads:
parser.exe -t user.dmp
Show thread w/ specific TID:
parser.exe -t 1337 user.dmp
Show foreground thread:
parser.exe -t main user.dmp
Show a memory page at a specific address:
parser.exe -dump 0x7ff00 user.dmp
Building
You can build it yourself using the appropriate build script for your platform in the build directory. It builds on Linux, Windows, OSX with the Microsoft, the LLVM Clang and GNU compilers.
Here is an example on Windows:
udmp-parser>cd src\build
udmp-parser\src\build>build-release.bat
udmp-parser\src\build>cmake .. -GNinja
