Instance Method Details

#pointer ⇒ Object

Callback factory methods.

WARNING: If your Ruby code doesn’t retain a reference to the

FFI::Function object after passing it to a C function call,
it may be garbage collected while C still holds the pointer,
potentially resulting in a segmentation fault.
