For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Header guards are little pieces of code that protect the contents of a header file from being included more than once. Header guards are implemented through the use of preprocessor directives. The C/C++ preprocessor directives all start with the # character. You are already familiar with some (#include, #define).
How do you use header guards in C++?
Header guards are little pieces of code that protect the contents of a header file from being included more than once. Header guards are implemented through the use of preprocessor directives. The C/C++ preprocessor directives all start with the # character. You are already familiar with some (#include, #define).
What do header guards protect against C++?
Header guards are designed to ensure that the contents of a given header file are not copied more than once into any single file, in order to prevent duplicate definitions.
What is the purpose of the include guard in a header file?
In the C and C++ programming languages, an #include guard, sometimes called a macro guard, header guard or file guard, is a particular construct used to avoid the problem of double inclusion when dealing with to include directive.
How do I use Index in header files?
#index is often used to make header files idempotent by defining a token once the file has been included and checking that the token was not set at the top of that file. This prevents from the multiple inclusion of same header file multiple time. Suppose you have included this header file in multiple files.
What do header guards protect against?
Header guards are designed to ensure that the contents of a given header file are not copied more than once into any single file, in order to prevent duplicate definitions. Note that header guards do not prevent the contents of a header file from being copied (once) into separate project files.
What happens if a header guard is omitted from a header file?
If the header guard strictly conforms to the pattern that compilers expect, then inclusions of that header other than the first have absolutely no effect: the file isn't re-read from disk, nor is it re-tokenised or re-preprocessed. This can result in a noticeable, albeit minor, improvement to compilation time.
