Yes, since one of the requirements of netCDF is that it support a Fortran
interface and permit full access to data written with any netCDF interface
from Fortran programs, it necessarily includes several vestiges of the
Fortran data model.

A single ncrecput() call can write a block of data containing mixed types,
so a series of of ncrecput() calls can probably do what you are attempting.
I have to qualify that with "probably" because I don't know all the
constraints you are under, for example, whether it's possible for you to
make "Ntotal" the record dimension for your dataset.
