## Remarks

`file`
The name of the file that that contains [MIDL command line options](https://msdn.microsoft.com/library/windows/desktop/aa366839).
## Remarks
All options for the conversion of an IDL file to a TLB file must be given in `file`; MIDL command-line options cannot be specified on the linker's command line. If /MIDL is not specified, the MIDL compiler will be invoked with only the IDL file name and no other options.
The file should contain one MIDL command-line option per line.
