F77 -> C routine communication

[Roy Smith]

I have a program which has f77 and C modules (main in fortran,
much of the I/O in C).  On the fortran side I have declared
"character*512 (512)".  If I want to pass this 512x512 array of
characters to a C routine, how should I declare the formal
parameter?
