Description Details Author(s) See Also

Provides an easy way to fill an environment with active bindings that call a C++ function.

Use LinkingTo: bindrcpp in DESCRIPTION and #include <bindrcpp.h> in your C++ headers and/or modules to access the C++ functions provided by this package:

create_env_string() creates an environment with active bindings, with names given as a character vector. Access of these bindings triggers a call to a C++ function with a fixed signature (GETTER_FUNC_STRING); this call contains the name of the binding (as character) and an arbitrary payload (PAYLOAD, essentially a wrapped void*).
create_env_symbol() is similar, the callback function accepts the name of the binding as symbol instead of character (GETTER_FUNC_SYMBOL).
populate_env_string() and populate_env_symbol() populate an existing environment instead of creating a new one.
