[cfe-dev] to judge whether a function it is a C/C++ standard library function or not

[Gábor Kozár]

Hi,

The simplest is to check whether the function is in the std:: namespace -
although this only works for C++ headers.
A better method might be to get the SourceLocation of the FunctionDecl
(e.g. with getLocStart()) and then use SourceManager :: isInSystemHeader
and isInExternCSystemHeader.
