13 | Module Name: | |
14 | ||
15 | UnixThunk.c | |
16 | ||
17 | Abstract: | |
18 | ||
19 | Since the SEC is the only program in our emulation we | |
20 | must use a Tiano mechanism to export APIs to other modules. | |
21 | This is the role of the EFI_UNIX_THUNK_PROTOCOL. | |
22 | ||
23 | The mUnixThunkTable exists so that a change to EFI_UNIX_THUNK_PROTOCOL | |
24 | will cause an error in initializing the array if all the member functions | |
25 | are not added. It looks like adding a element to end and not initializing | |
26 | it may cause the table to be initaliized with the members at the end being | |
27 | set to zero. This is bad as jumping to zero will crash. | |
28 | ||
29 | ||
30 | gUnix is a a public exported global that contains the initialized | |
31 | data. | |
