Hello stormdos-develop,

EXECUTABLES AND DLLs HANDLING SKETCH:


[THREAD]

fs_current_dir
next_sibling_thread (the threads of one app are called "siblings" here)
app_handle ("parent" application)


[APPLICATION]

fs_opened_files_list

page_directory_object

threads_count
main_thread

module_handle

should we need heap_support here?


[MODULE] (a lot of modules for every application)

image_handle
dll_modules (MODULEs used as DLLs and needed by this module i.e. dependencies)


[IMAGE] (usually only one, at least for system DLLs)

reference_counter (how many MODULES use this image)
file_path
image_filename
template_ptr (if it's cached then it won't be loaded from a file but from memory instead)

dlls_needed (names of DLLs)

------------------

Execution process:

#find allocated image with that name:
 if no then load and register, enumerate needed DLLs;
  else increment image.reference_counter
  
#allocate module
  - load image
  - call #allocate module(module.image_handle.next_dll)
  
-------------------  
  
Shutdown process:

#freemodule(module)
 decrement image reference
 free memory used by module using specified PAGEDIR
 call #freemodule(next_dll)
