SUMMARY
The MIDL /char command line switch is used to ensure that the MIDL compiler
and the Visual C++ compiler operate together correctly for all char types.
By default, a MIDL char is unsigned whereas a default char in Visual C++ is
signed. The MIDL /char switch is used to force MIDL to generate signed or
unsigned chars and can be used to match the type generated by the Visual
C++ compiler.
The /char signed option indicates that the C-compiler char type is signed.Using /char signed results in MIDL chars that are unsigned. Therefore, the types will be mismatched and the project will not compile. Use /char unsigned to generate MIDL signed chars. The same documentation also states the following: The /char unsigned option indicates that the C-compiler char type is unsigned.Using /char unsigned results in MIDL chars that are signed. Therefore, the types will be mismatched and the project will not compile. Use /char signed to generate MIDL unsigned chars.
