/FI (Name Forced Include File)

  • Article

Causes the preprocessor to process the specified header file.

This option has the same effect as specifying the file with double quotation marks in an #include directive on the first line of every source file specified on the command line, in the CL environment variable, or in a command file. If you use multiple /FI options, files are included in the order they are processed by CL.
