Additional parameters beyond parent class:
- prefixText - list of strings to prefix generated header with
(usually a copyright statement + calling convention macros).
- protectFile - True if multiple inclusion protection should be
generated (based on the filename) around the entire header.
- protectFeature - True if #ifndef..#endif protection should be
generated around a feature interface in the header file.
- genFuncPointers - True if function pointer typedefs should be
generated
- protectProto - If conditional protection should be generated
around prototype declarations, set to either '#ifdef'
to require opt-in (#ifdef protectProtoStr) or '#ifndef'
to require opt-out (#ifndef protectProtoStr). Otherwise
set to None.
- protectProtoStr - #ifdef/#ifndef symbol to use around prototype
declarations, if protectProto is set
- apicall - string to use for the function declaration prefix,
such as APICALL on Windows.
- apientry - string to use for the calling convention macro,
in typedefs, such as APIENTRY.
- apientryp - string to use for the calling convention macro
in function pointer typedefs, such as APIENTRYP.
- indentFuncProto - True if prototype declarations should put each
parameter on a separate line
- indentFuncPointer - True if typedefed function pointers should put each
parameter on a separate line
- alignFuncParam - if nonzero and parameters are being put on a
separate line, align parameter names at the specified column
- genEnumBeginEndRange - True if BEGIN_RANGE / END_RANGE macros should
be generated for enumerated types
- genAliasMacro - True if the OpenXR alias macro should be generated
for aliased types (unclear what other circumstances this is useful)
- aliasMacro - alias macro to inject when genAliasMacro is True
- misracstyle - generate MISRA C-friendly headers
- misracppstyle - generate MISRA C++-friendly headers"""
