[cfe-dev] QualType

[Monalisa Rout via cfe-dev]

Hello Eli,

I am able to crate QualType for all types of pointers by using
ASTContext::getPointerType(). But again I am stuggling for *const int*.
I am trying to use this method ASTContext
<http://swtv.kaist.ac.kr/~bookman01/classclang_1_1ASTContext.html#a5930b71a916bc5b4eea3b69160ef6810>
::GetBuiltinType
<http://swtv.kaist.ac.kr/~bookman01/classclang_1_1ASTContext.html#a17e4f89e87ad7a5a29c5333b478a384e>
(unsigned <http://swtv.kaist.ac.kr/~bookman01/classunsigned.html> ID,
GetBuiltinTypeError
<http://swtv.kaist.ac.kr/~bookman01/classclang_1_1ASTContext.html#aebda31ac75861bbfdb20ad6c54a2dc50>
&Error
<http://swtv.kaist.ac.kr/~bookman01/namespaceclang.html#a19a831d7318de60497404ddf66dde9d4a902b0d55fddef6f8d651fe1035b7d4bd>),
but not sure if this is the method needs to be used and if so what is the
ID value for "int".

Once I get QualType, I can call the addConst
<https://clang.llvm.org/doxygen/classclang_1_1QualType.html#a43a8b5d4a9d63c319ad978252426379a>
() to get const type qualifier.

Regards,
Mona
