void checkCallExpr(const CallExpr *CE, CheckerContext &C) { // Get the name of the function being called const FunctionDecl *FD = CE->getDirectCallee(); if (FD) { StringRef FunctionName = FD->getName(); // Check if the called function is a security vulnerability if (FunctionName.equals("strcpy")) { C.emitWarning("Using strcpy is a security vulnerability. Use strncpy instead."); } // Check if the called function is deprecated if (FunctionName.equals("old_function")) { C.emitWarning("This function is deprecated. Use new_function instead."); } } }Package/library determination: The CheckerContext::getCalleeName method does not determine or specify any particular package or library, as it only returns the name of the function being called. The package or library issue would need to be addressed separately within the analysis tool or program.
