Source: R/tcc_ptr_utils.R
tcc_data_ptr.Rd

Treats ptr_ref as a pointer to a pointer and returns the pointed address as an external pointer. This is useful for fields like void** or T**.

Usage

tcc_data_ptr(ptr_ref)

Arguments

ptr_ref

External pointer to a pointer value (e.g., address of a field).

Value

An external pointer tagged "rtinycc_borrowed". Not owned by Rtinycc and never freed on garbage collection. Do not pass to tcc_free().
