The answer is "it depends".  Which C are you using and which Fortran?
For UNIX, AEGIS, and VMS, the answer is in (Fortran documentation,
C documentation, C documentation) -- from memory.  (Yes, the answer
really is there in a complete UNIX documentation set.  Or use f2c.)
The usual technique in UNIX is to pass an extra int parameter for each
character*(_) variable giving the length for that variable, after
all the other parameters.
