/mktyplib203

midl /mktyplib203

Examples

midl /mktyplib203 myoldodl.odl 
midl /mktyplib203 oldhabit.idl 
 

Remarks

The /mktyplib203 switch forces the MIDL compiler to parse the input file in much the same manner as MKTYPLIB.EXE, version 2.03, would handle the file. In order to use this switch, the input file must follow the ODL syntax exactly — you cannot place any statements outside of the library block. Specifically, using the /mktyplib203 switch resolves the following discrepancies between MKTYPLIB and MIDL:

• MKTYPLIB typdef syntax is required for struct, union and enum data types.
• GUIDs in the header files are defined with a macro that can be conditionally compiled to generate either a GUID predefinition or an instantiated GUID.
• The base type BOOL is represented as a VARIANT_BOOL, which is defined as a short.

See Differences Between MIDL and MKTYPLIB for a more detailed description of these differences and a discussion of the differences between MKTYPLIB and MIDL that cannot be resolved by using the /mktyplib203 switch.
