Response Files

Response Files

As an alternative to placing all the options on the command line, the MIDL compiler accepts response files that contain switches and arguments. A response file is a text file containing one or more MIDL compiler command-line options. Unlike a command line, a response file allows multiple lines of options and file names. This may be useful due to limitations of your build environment or as a convenience for your build process. You can specify a MIDL response file as:

midl @filename


Specifies the name of the response file. The response file name must immediately follow the @ character with no white space between the @ character and the response file name.

Options in a response file are interpreted as if they were present at that place in the MIDL command line. Each argument in a response file must begin and end on the same line. You cannot use the backslash character (\) to concatenate lines.

MIDL supports command-line arguments that include one or more response files, combined with other command-line switches:

midl -Oicf @midl1.rsp -envwin32 @midl2.rsp itf.idl

The MIDL compiler does not support nested response files.
