| indexDemoClose {rindex} | R Documentation |
Function indexDemoOpen creates an external pointer pointing to an integer vector of length n, indexDemoClose frees the memory linked to the pointer.
indexDemoOpen(n = 10) indexDemoClose(extPtr)
extPtr |
the external pointer returned by indexDemoOpen |
n |
the length of the vector stored in C RAM |
If the returned pointer is removed finalization happens at the next gc(), if indexDemoClose is used on the pointer then finalization happens immediately, if the pointer is then removed, the finalizer is called again at the next gc() (but doesn't finalize again).
Function indexDemoOpen returns an external pointer, indexDemoClose returns the integer vector previously linked by the pointer.
