specific __attribute__((__unused__)), which breaks MSVC compilation... I'll use this as a reminder that gnu-efi is compiled with more than GNU toolchains, and that contributors might want to be careful about adding GNU-specific extensions... This patch does the following: Create a new eficompiler.h header that sets all compiler-specific options and extensions Create a new EFI_UNUSED macro to be used in lieu of __attribute__((__unused__)) and applies it to the relevant sources Move the ALIGN(x) macro, previously defined in efisetjmp.h to the new header Oh, and it also fixes a bunch of trailing whitespaces (because my code editor is set to do just that by default).

Routine Description:
|
|
|
|
Check to see if DevicePath exists for a given Protocol. Return Error if it
|
|
exists. Return GlobalIoFuncs set match the DevicePath
|
|
|
|
Arguments:
|
|
|
|
DevicePath - to operate on
|
|
Protocol - to check the DevicePath against
|
|
ErrorStr - ASCII string to display on error
|
|
GlobalIoFncs - Returned with DeviceIoProtocol for the DevicePath
|
|
|
|
Returns:
|
|
|
|
Pass or Fail based on wether GlobalIoFncs where found
