The type then looks like this:
(gdb) pt $_tlb->process_environment_block->process_parameters
type = struct rtl_user_process_parameters {
DWORD32 maximum_length;
DWORD32 length;
DWORD32 flags;
DWORD32 debug_flags;
void *console_handle;
DWORD32 console_flags;
void *standard_input;
void *standard_output;
void *standard_error;
unicode_string current_directory;
void *current_directory_handle;
unicode_string dll_path;
unicode_string image_path_name;
unicode_string command_line;
void *environment;
DWORD32 starting_x;
DWORD32 starting_y;
DWORD32 count_x;
DWORD32 count_y;
DWORD32 count_chars_x;
DWORD32 count_chars_y;
DWORD32 fill_attribute;
DWORD32 window_flags;
DWORD32 show_window_flags;
unicode_string window_title;
unicode_string desktop_info;
unicode_string shell_info;
unicode_string runtime_data;
} *
It's mainly useful to get the current directory, or the full command line:
(gdb) p $_tlb->process_environment_block->process_parameters->current_directory
$1 = {
length = 26,
maximum_length = 520,
buffer = 0xe36c8 L"C:\\src\\tests\\"
}
(gdb) p $_tlb->process_environment_block->process_parameters->command_line
$2 = {
length = 94,
maximum_length = 96,
buffer = 0xe32aa L"\"C:\\gdb\\build64\\gdb-git\\gdb\\gdb.exe\" access.exe"
}
The type names are all lowercase because the existing types created
by windows_get_tlb_type are also lowercase.
Type unicode_string is documented at [1].
The official documentation [2] for rtl_user_process_parameters is limited,
so I've used this other page [3].

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
