Hi,
I'm trying to use clang's ParseAST() and ASTConsumer to extract all c function
declarations in a source file, and then output these function declarations into
another file.
It's all good unless there is some unknown type name exists. For example,
my_type foo(int x) { /*...*/ } // "my_type" is just a type identifier
whose definition is missed in this translation unit.
When I use getReturnType() in RecursiveASTVisitor::VisitFunctionDecl(), it will
return type "int". So my program will output
int foo(int x);
instead of
my_type foo(int x);
I'm curious why "my_type" will be parsed as of type "int".
When parsing this source code, clang will report an error saying "error:
unknown type name 'my_type'". So I think clang knows it's a type (unknown type
is also a type I think).
Thanks!
