Documentation for sub nativecast, assembled from the following types:
sub nativecast(, ) is export(:DEFAULT)
This will cast the Pointer
$source to an object of
$target-type. The source pointer will typically have been obtained from a call to a native subroutine that returns a pointer or as a member of a
struct, this may be specified as
void * in the
C library definition for instance, but you may also cast from a pointer to a less specific type to a more specific one.
As a special case, if a Signature is supplied as
$target-type then a
subroutine will be returned which will call the native function pointed to by
$source in the same way as a subroutine declared with the
native trait. This is described in Function Pointers.
