16 | Abstract: | |
17 | ||
18 | This protocol allows an EFI driver in the Unix emulation environment | |
19 | to make Posix calls. | |
20 | ||
21 | NEVER make an Unix call directly, always make the call via this protocol. | |
22 | ||
23 | There are no This pointers on the protocol member functions as they map | |
24 | exactly into Unix system calls. | |
