manw

manw is a very simple and fast command line search tool for Windows API written in Go.

Why?

Because sometimes open the browser takes too much time.

Usage

NAME

  ./manw [OPTION...] [STRING]
          
OPTIONS:

  -f, --function  string  Search for a Windows API Function.
  -s, --structure string  Search for a Windows API Structure.    
  -k, --kernel    string  Search for a Windows Kernel Structure.
  -t, --type      string  Search for a Windows Data Type.
  -a, --arch      string  Specify the architecture you are looking for.
  -n, --syscall   string  Search for a Windows Syscall ID. If you don't use -a the default value is "x86".
  -c, --no-cache  bool    Disable the caching feature.

Examples

$ ./manw -f createprocessw
CreateProcessW function (processthreadsapi.h) - Win32 apps

Exported by: Kernel32.dll

Number of arguments: 10

Creates a new process and its primary thread. The new process runs in the security context of the calling process. (Unicode)

BOOL CreateProcessW(
  [in, optional]      LPCWSTR               lpApplicationName,
  [in, out, optional] LPWSTR                lpCommandLine,
  [in, optional]      LPSECURITY_ATTRIBUTES lpProcessAttributes,
  [in, optional]      LPSECURITY_ATTRIBUTES lpThreadAttributes,
  [in]                BOOL                  bInheritHandles,
  [in]                DWORD                 dwCreationFlags,
  [in, optional]      LPVOID                lpEnvironment,
  [in, optional]      LPCWSTR               lpCurrentDirectory,
  [in]                LPSTARTUPINFOW        lpStartupInfo,
  [out]               LPPROCESS_INFORMATION lpProcessInformation
);

Return value: If the function succeeds, the return value is nonzero.If the function fails, the return value is zero.

Example code:

        LPTSTR szCmdline = _tcsdup(TEXT("C:\\Program Files\\MyApp -L -S"));
        CreateProcess(NULL, szCmdline, /* ... */);

$ ./manw -t callback

Data Type: CALLBACK

The calling convention for callback functions. This type is declared in WinDef.h as follows: #define CALLBACK __stdcall CALLBACK, WINAPI, and APIENTRY are all used to define functions with the __stdcall calling convention. Most functions in the Windows API are declared using WINAPI. You may wish to use CALLBACK for the callback functions that you implement to help identify the function as a callback function.

$ ./manw -k _token_control
//0x28 bytes (sizeof)
struct _TOKEN_CONTROL
{
    struct _LUID TokenId;                                                   //0x0
    struct _LUID AuthenticationId;                                          //0x8
    struct _LUID ModifiedId;                                                //0x10

If no flag is specified manw is going to use -f flag by default.

⚠️ Warning

The scraper relies on the way the pages used by the project (e.g. google, MSDN, etc) are implemented so keep in mind that if it changes the search might not work. That being said always keep your manw up-to-date and please let me know if you find any issue.

Known issues:

Data type search might show a very weird output depending the data you search.
Currently the kernel struct info search supports Windows Vista 32bits kernel only. I do have plans to support other versions in the future.
I'm also always trying to improve the code (e.g. performance, best practices, etc.) since I started it as a study project.

Special Thanks

@merces for the core idea and all the support.
