/**
|
|
UEFI entry point for an application that will in turn call the
|
|
ShellAppMain function which has parameters similar to a standard C
|
|
main function.
|
|
|
|
An application that uses UefiShellCEntryLib must have a ShellAppMain
|
|
function as prototyped in Include/Library/ShellCEntryLib.h.
|
|
|
|
Note that the Shell uses POSITIVE integers for error values, while UEFI
|
|
uses NEGATIVE values. If the application is to be used within a script,
|
|
it needs to return one of the SHELL_STATUS values defined in Protocol/Shell.h.
|
|
|
|
@param ImageHandle The image handle of the UEFI Application.
|
|
@param SystemTable A pointer to the EFI System Table.
|
|
|
|
@retval EFI_SUCCESS The application exited normally.
|
|
@retval Other An error occurred.
