The Response File Command
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.
Switch Options
midl @response_file
-
response_file
-
Specifies the name of a response file. The response file name must immediately follow the @ character. No white space is allowed between the @ character and the response file name.
Remarks
As an alternative to placing all options associated with a switch on the command line, the MIDL compiler accepts response files that contain switches and arguments. Options in a response file are interpreted as if they are present in that location in the MIDL command line.
Each argument in a response file must begin and end on the same line. The backslash character (\) cannot be used to concatenate lines. When it is part of a quoted string in the response file, the backslash character can only be used before another backslash or before a double quotation mark character ("). When it is not part of a quoted string, the backslash character can only be used before a double quotation mark character.
MIDL supports command-line arguments that include one or more response files combined with other command-line switches.
The MIDL compiler does not support nested response files.
Examples
**midl @midl.rsp**
midl -Oicf @midl1.rsp -env win32 @midl2.rsp itf.idl
