CIF-class: Class to represent external Call InterFace (CIF)

In omegahat/Rffi: Interface to libffi to dynamically invoke arbitrary compiled routines at run-time without compiled bindings

Class to represent external Call InterFace (CIF)

Description

This class represents a call interface for invoking native routines via libffi. A CIF stands for Call InterFace and consists of a C-level object describing the call and also information about which parameters are mutable pointers.

Objects from the Class

Objects can be created by calls of the form new("CIF", ...). Typically, one uses the CIF constructor function.

Slots

ref:

Object of class "externalptr" representing the C object that is used when invoking a routine using callCIF.

pointerParameters:

Object of class "logical" indicating which of the parameters (if any) are pointers and hence potentially mutable in the call. These are used to return not only the value from the routine, but any of the inputs that might have been mutated.

Methods

No methods defined with class "CIF" in the signature.
