2026-02-24MdePkg: Replace include guards with #pragma onceMichael Kubacki1-4/+1
Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki <michael.kubacki@microsoft.com>

V2: - Rename "List" to "FirstEntry" and "Node" to "SecondEntry" to clarify that "FirstEntry" does not need to be the doubly-linked list's head node.

2017-01-09MdePkg/BaseLib: Add safe string functions that convert str to valueHao Wu1-1/+165
Add the following 8 APIs: [Ascii]StrDecimalToUintnS [Ascii]StrDecimalToUint64S [Ascii]StrHexToUintnS [Ascii]StrHexToUint64S These safe version APIs are used to enhance their counterpart (APIs without trailing 'S' in function names). These safe version APIs perform checks to the input string and will return relative status to reflect the check result: When the input string exceeds the range of UINTN/64, these APIs will return RETURN_UNSUPPORTED and store MAX_UINTN/64 in the output data. When no conversion can be performed for the input string, these APIs will return RETURN_SUCCESS and store 0 in the output data. The optional parameter 'EndPointer', if provided, will point to the character that stopped the scan.
