| getDLLRegisteredRoutines {base} | R Documentation |
This function allows us to query the set of routines
in a DLL that are registered with R to enhance
dynamic lookup, error handling when calling native routines,
and potentially security in the future.
This function provides a description of each of the
registered routines in the DLL for the different interfaces,
i.e. .C, .Call, .Fortran
and .External.
getDLLRegisteredRoutines(dll)
dll |
a character string or DLLInfo object (as returned by
getLoadedDLLs).
|
This takes the registration information after it has been registered and processed by the R internals. In other words, it uses the extended information
A list with four elements corresponding to the routines
registered for the .C, .Call, .Fortran and .External interfaces.
Each element is a list with as many elements as there were
routines registered for that interface.
Each element identifies a routine and is an object
of class NativeSymbolInfo.
An object of this class has the following fields:
name |
the registered name of the routine (not necessarily the name in the C code). |
address |
the memory address of the routine as resolved in the
loaded DLL. This may be NULL if the symbol has not yet been
resolved. |
dll |
an object of class DLLInfo describing the DLL.
This is same for all elements returned. |
numParameters |
the number of arguments the native routine is to be called with. In the future, we will provide information about the types of the parameters also. |
