I think that the definition may be somehow obtainable by using the cursor's extents, but I don't really know how (what function to use).
You can use this simple code to get prototype of a function ( name, return type, count of arguments and arguments[name,data type]).
string Convert(const CXString& s) { string result = clang_getCString(s); clang_disposeString(s); return result; } void print_function_prototype(CXCursor cursor) { // TODO : Print data! auto type = clang_getCursorType(cursor); auto function_name = Convert(clang_getCursorSpelling(cursor)); auto return_type = Convert(clang_getTypeSpelling(clang_getResultType(type))); int num_args = clang_Cursor_getNumArguments(cursor); for (int i = 0; i < num_args; ++i) { auto arg_cursor = clang_Cursor_getArgument(cursor, i); auto arg_name = Convert(clang_getCursorSpelling(arg_cursor)); if (arg_name.empty()) { arg_name = "no name!"; } auto arg_data_type = Convert(clang_getTypeSpelling(clang_getArgType(type, i))); } } CXChildVisitResult functionVisitor(CXCursor cursor, CXCursor /* parent */, CXClientData /* clientData */) { if (clang_Location_isFromMainFile(clang_getCursorLocation(cursor)) == 0) return CXChildVisit_Continue; CXCursorKind kind = clang_getCursorKind(cursor); if ((kind == CXCursorKind::CXCursor_FunctionDecl || kind == CXCursorKind::CXCursor_CXXMethod || kind == CXCursorKind::CXCursor_FunctionTemplate || \ kind == CXCursorKind::CXCursor_Constructor)) { print_function_prototype(cursor); } return CXChildVisit_Continue; }
