* are implemented here are actually implemented using VPI routines.
*
* NOTE 2: The routines and definitions of the tf_ library were
* clearly not designed to account for C++, or even ANSI-C. This
* header file attempts to fix these problems in a source code
* compatible way. In the end, though, it is not completely
* possible. Instead, users should not use this or the acc_user.h
* header files or functions in new applications, and instead use the
* more modern vpi_user.h and VPI functions.
*
* This API is provided by Icarus Verilog only to support legacy software.
