This is a very small library (32k) that helps you to develop for UEFI under Linux (and other POSIX systems). It was greatly

inspired by [gnu-efi](https://sourceforge.net/projects/gnu-efi) (big big kudos to those guys), but it is a lot smaller,
|

easier to integrate (works with Clang and GNU gcc both) and easier to use because it provides a POSIX like API.

By default it uses the host native's GNU gcc + ld, creates a shared object and converts that into .efi file. If `USE_LLVM`

is given, then LLVM CLang + lld used, and native PE is generated, no conversion involved.

BOOLEAN -> boolean_t, UINTN -> uintn_t, EFI_MEMORY_DESCRIPTOR -> efi_memory_descriptor_t, and of course
|
||||
EFI_BOOT_SERVICES -> efi_boot_services_t.
|
||||
|
||||
That header also provides an UEFI ABI wrapper, exactly the same as in gnu-efi, and functions to exit Boot Services
|
||||
and to dump memory for your convenience.
|
||||
Calling UEFI functions is as simple as with EDK II, just do the call, no need for "uefi_call_wrapper":
|
||||
```c
|
||||
ST->ConOut->OutputString(ST->ConOut, L"Hello World!\r\n");
|
||||
```
|
||||
|
||||
| Function | Description |
|
||||
|-----------------------|----------------------------------------------------|
|
||||
| `uefi_call_wrapper()` | call a function with UEFI ABI (provided by crt0) |
|
||||
| `uefi_exit_bs()` | leave this UEFI bullshit behind (provided by crt0) |
|
||||
| `uefi_dumpmem()` | dump memory (provided by libuefi.a) |
|
||||
There are two additional, non-POSIX calls in the library. One is `exit_bs()` to exit Boot Services, and the other is
|
||||
a non-blocking `getchar_ifany()`.

Unlike gnu-efi, POSIX-UEFI does not pollute your application with unused GUID variables. It only provides header definitions,

so you must create each GUID instance if and when you need them.

Unlike gnu-efi, POSIX-UEFI does not pollute your application's namespace with unused GUID variables. It only provides
|

header definitions, so you must create each GUID instance if and when you need them.
|

|
||||
Example:
|

```c
|

efi_guid_t gopGuid = EFI_GRAPHICS_OUTPUT_PROTOCOL_GUID;
|

efi_gop_t *gop = NULL;
|

status = BS->LocateProtocol(&gopGuid, NULL, (void**)&gop);
|
||||
```
|
||||
|
||||
Also unlike gnu-efi, POSIX-UEFI does not provide standard EFI headers. It expects that you have installed those under
|
||||
/usr/include/efi from EDK II or gnu-efi with your distro's package management solution, and POSIX-UEFI makes it possible
|
||||
for you to use those system wide headers. POSIX-UEFI itself ships the very minimum set of typedefs and structs.

String formating is limited; only supports padding via number prefixes, `%d`, `%x`, `%X`, `%c`, `%s`, `%q` and

`%p`. Because it operates on wchar_t, it also supports the non-standard `%C` (printing an UTF-8 character, needs
