Add type for $_tlb->process_environment_block->process_parameters
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].
