SEXP INTERNAL ( SEXP  x )

inline

Get function accessed via .Internal().

Parameters:

x	Pointer to a CXXR::Symbol (checked).

Returns:

If x is associated with a function invoked in R via .Internal(), then a pointer to the appropriate CXXR::BuiltInFunction, otherwise a null pointer.

void SET_INTERNAL	(	SEXP	x,
		SEXP	v
	)

Associate a Symbol with a .Internal() function.

Parameters:

x	Pointer to a CXXR::Symbol (checked).
v	Pointer to the CXXR::BuiltInFunction (checked) to be associated by this symbol. A null pointer is permissible, and signifies that any previous association of sym with a function is to be removed from the table.
