There are a few things I would do differently, such as heap overflow checking.  But for the particular task of providing a wrapper to the read system call I would use a different interface.  Why don't you allocate the buffer in Scheme before calling read?  That would simplify the C code (avoiding GC issues) and would be more efficient.
