Detailed Description
Implementation of class GCRootBase.
Function Documentation
| void R_PreserveObject | ( | SEXP | object | ) |
Protect object against garbage collection.
This is intended for long-term protection, for which PROTECT() etc. would be inappropriate.
- Parameters:
-
object Pointer to the object to be preserved. It is permissible for this to be a null pointer.
| void R_ReleaseObject | ( | SEXP | object | ) |
Remove object's protection against garbage collection.
- Parameters:
-
object Pointer to the object whose protection is to be removed. It is permissible (but pointless) for this to be a pointer to an object that is not currently protected by R_PreserveObject(), but in that case R_ReleaseObject() has no effect.
