Detailed Description
CallExpr - Represents a function call (C99 6.5.2.2, C++ [expr.call]).
CallExpr itself represents a normal function call, e.g., "f(x, 2)", while its subclasses may represent alternative syntax that (semantically) results in a function call. For example, CXXOperatorCallExpr is a subclass for overloaded operator calls that use operator syntax, e.g., "str1 + str2" to resolve to a function call.

◆ Create()

Create a call expression.
- Parameters
-
Fn The callee expression, Args The argument array, Ty The type of the call expression (which is not the return type in general), VK The value kind of the call expression (lvalue, rvalue, ...), RParenLoc The location of the right parenthesis in the call expression. FPFeatures Floating-point features associated with the call, MinNumArgs Specifies the minimum number of arguments. The actual number of arguments will be the greater of Args.size() and MinNumArgs. This is used in a few places to allocate enough storage for the default arguments. UsesADL Specifies whether the callee was found through argument-dependent lookup.
Note that you can use CreateTemporary if you need a temporary call expression on the stack.
