A header file that uses a non-portable mechanism to prevent multiple inclusion.
Known direct subtypes
Gets the element to blame for this bad include guard pattern.
Holds if this file was compiled as C (at any point).
Holds if this file was compiled as C++ (at any point).
Holds if this file was compiled by a Microsoft compiler (at any point).
Gets the source of this element: either itself or a macro that expanded to this element.
Holds if this file may be from a library.
Holds if this file may be from source. This predicate holds for all files except the dummy file, whose name is the empty string, which contains declarations that are built into the compiler.
Gets a file or sub-folder in this container.
Gets a declaration in this file.
Gets a file in this container.
Gets a sub-folder in this container.
Gets the name of a primary CodeQL class to which this element belongs.
Gets a top-level element declared in this file.
Gets the absolute, canonical path of this container, using forward slashes as path separator.
Gets a file that is directly included from this file (using a pre-processor directive like
Gets the base name of this container including extension, that is, the last segment of its absolute path, or the empty string if it has no segments.
Gets the closest
Gets the extension of this container, that is, the suffix of its base name after the last dot character, if any.
Gets the remainder of the base name after the first dot character. Note that the name of this predicate is in plural form, unlike
Gets the file in this container that has the given
Gets the primary file where this element occurs.
Gets the sub-folder in this container that has the given
Gets the primary location of this element.
Gets the metric file.
Gets the parent container of this file or folder, if any.
Gets the parent scope of this
Gets the relative path of this file or folder from the root folder of the analyzed source location. The relative path of the root folder itself is the empty string.
Gets the short name of this file, that is, the prefix of its base name up to (but not including) the first dot character if there is one, or the entire base name if there is not. For example, if the full name is “/path/to/filename.a.bcd” then the short name is “filename”.
Gets the stem of this container, that is, the prefix of its base name up to (but not including) the last dot character if there is one, or the entire base name if there is not.
Holds if this element is affected in any way by a macro. All elements that are totally or partially generated by a macro are included, so this is a super-set of
Holds if this
Holds if this
Holds if this element comes from a macro expansion. Only elements that are entirely generated by a macro are included - for elements that partially come from a macro, see
Holds if this header file does not contain any declaration entries or top level declarations. For example it might be: - a file containing only preprocessor directives and/or comments - an empty file - a file that contains non-top level code or data that’s included in an unusual way
Gets a textual representation of the path of this container.
Holds if this file uses the given macro.
