From 6c3fa13c9114e39529652a6891c36ab3c8a1d6ca Mon Sep 17 00:00:00 2001 From: qhuang8 Date: Fri, 19 Mar 2010 00:25:47 +0000 Subject: Define VERIFY_SIZE_OF macro to verify size of basic UEFI Data types. This should be equivalent with previous implementation. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10283 6f19259b-4bc3-4df7-8a09-765794883524 --- MdePkg/Include/Base.h | 41 ++++++++++++++++++++++++++--------------- 1 file changed, 26 insertions(+), 15 deletions(-) (limited to 'MdePkg/Include') diff --git a/MdePkg/Include/Base.h b/MdePkg/Include/Base.h index 5b1f418d1a..a2d275223c 100644 --- a/MdePkg/Include/Base.h +++ b/MdePkg/Include/Base.h @@ -27,24 +27,35 @@ WITHOUT WARRANTIES OR REPRESENTATIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED. // #include + +/** + Verifies the storage size of a given data type. + + This macro generates a divide by zero error or a zero size array declaration in + the preprocessor if the size is incorrect.
