Would a uniform byte vector (or array if you need more than one
dimension) work?

(make-uniform-vector size #\nul &fill)

You can use the helper procedures uniform-vector-read! and
uniform-vector-write to read and write data from/to a port or a file
descriptor. Uniform vectors and arrays are documented in the Guile
manual, (guile)->Compound Data Types->Arrays->Uniform Arrays.
