Dear R-help, Sorry if this is way obvious. (It just wasn't for me...) Do all parameters passed to Fortran routines from C need to be declared as pointers? In various header files (e.g., Linpack.h), that seems to be the case.
Yes. Fortran passes by reference.
Also, what type should I declare in front of F77_NAME() for a subroutine? void?
Yes.
