Function Documentation

void Rf_ppsRestoreSize ( size_t new_size )

Restore C pointer protection stack to a previous size.

Restore the C pointer protection stack to a previous size by popping elements off the top.

Parameters:

new_size The size to which the stack is to be restored. Must not be greater than the current size.

Deprecated:: This is an interface for C code to call CXXR::ProtectStack::restoreSize(), which may cease to be available in future. In C++, use of the ProtectStack::Scope class is preferable.

size_t Rf_ppsSize ( )

Current size of C pointer protection stack.

Deprecated:: This is an interface for C code to call CXXR::ProtectStack::size(), which may cease to be public in future.
