Can libclang tell me if a function has weak linkage?
I am using the libclang C interface to Clang, and trying to figure out if the function definition at my current CXCursor has weak linkage, i.e. was declared with _attribute__((weak))
clang_Cursor_hasAttrs(cursor) tells me that the function with weak linkage does indeed have one or more attributes, but doesn't tell me which ones.
I have been looking through the documentation of libclang at https://clang.llvm.org/doxygen/group__CINDEX__CURSOR__MANIP.html and also at the header file clang-c/Index.h but cannot find any function to extract this information.
Is there a way to do this in the C interface, or do I need to use the underlying C++ interface of Clang to achieve this?

according to wikipedia:nm | grep someObjectFileshould outputa weak function symbol is marked with "W" if a weak default definition is available, and with "w" if it is notif it is marked with a U that would be external linkage... and T would be standard default linkage
