File TypeC++ Inline File
What is an INL file?
Source code file used by Microsoft C++ compilers; contains inline functions that can be included into C++ programs; used for storing reusable program components.
INL files can be used as an alternative to placing implementations of inline functions in header files (.H or .HPP files). Both INL files and header files can be inserted in C++ program code using the #include directive.
