isFnPointer: Queries function/routine pointer object

In omegahat/RClangSimple: R Interface to the clang parser's C API

Queries function/routine pointer object

Description

These functions allow us to determine if a CXType is a function pointer, and to get the information about the function pointer type.

Usage

isFnPointer(x)
getFnPointerInfo(field, cur = NULL,
                 toks = if(!is.null(cur))
                           sapply(children(cur), getCursorTokens),
                 useCanonical = FALSE) 

Arguments

x	the CXType being queried to determine if it is a function pointer type.
field	a CXType which is a C-level function pointer
cur	the CXCursor associated with the field CXType
toks	a list of the CXCursor objects within the cur cursor.
useCanonical	a logical value controlling whether we use the canonical type or high-level type. If this is TRUE, when we get the type for the pointer, we get the canonical version of this, i.e. ignore typedefs/aliases.

Value

An instance of an S3 class named FunctionPointerInfo which is a list with two elements:

returnType	the return type of the function type
params	the list of the parameter types of the function type
