| # Chrome Early Loading Framework (ELF) |
| |
| The Chrome Early Loading Framework provides a facility to execute code very |
| early during process startup before other imported DLLs (e.g., `kernel32`). This |
| is useful for dynamic patching of system functions (e.g., `NtMapViewOfSection`) |
| to implement advanced control over the process. |
| |
| Chrome's initial entry point on Windows is |
| [DllMain](https://docs.microsoft.com/en-us/windows/desktop/dlls/dllmain) in |
| `chrome_elf.dll` (defined in [chrome_elf_main.cc](./chrome_elf_main.cc)). The |
| [reorder-imports.py](../../build/win/reorder-imports.py) script is used at |
| build-time to ensure that `chrome_elf.dll` is the first import of `chrome.exe`. |
