Function Documentation

ShellCEntryLib()

EFI_STATUS EFIAPI ShellCEntryLib	(	IN EFI_HANDLE	ImageHandle,
		IN EFI_SYSTEM_TABLE *	SystemTable
	)

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.

Parameters

ImageHandle	The image handle of the UEFI Application.
SystemTable	A pointer to the EFI System Table.

Return values

EFI_SUCCESS	The application exited normally.
Other	An error occurred.
