Hello I'm working with clang libtooling. I need to take a .c file and print the names of all functions present and the lines the function declaration is in. In the ASTRecursive class I have function VisitFunctionDecl and have found the functions but am very confused how to find the line number of the Stmts.

Given a FunctionDecl *f, f->getSourceRange() is its source range (beginning and end). Given a SourceRange sr, sr.getBegin() gives you a SourceLocation which is the beginning of the range.
Look up the documentation / declarations of the classes mentioned for more details.

I want print these line or show them on the terminal. How can I do that? – Awaid Shaheen Jul 07 '15 at 11:32

Given a SourceLocation, you can use its `print` or `printToString` methods and pass it a `SourceManager` (possibly from your matched `ASTContext`). – tropicalmug Sep 21 '17 at 14:27
