UnixThunk.h
|

|
Abstract:
|
|
|
|
This protocol allows an EFI driver in the Unix emulation environment
|
|
to make Posix calls.
|
|
|
|
NEVER make an Unix call directly, always make the call via this protocol.
|
|
|
|
There are no This pointers on the protocol member functions as they map
|
|
exactly into Unix system calls.
