The C in v7 is, canonically, the language described in K&R, right?

I must be doing something dumb.

I am getting Webb Miller’s “s” editor built there, and I am down to one function.

/* chop_arg - chop a function's argument to a maximum length */

static chop_arg(fcn, arg, maxlen)

int (*fcn)();

int maxlen;

char *arg;

{

char save;

save = arg[maxlen];

arg[maxlen] = '\0';

fcn(arg);

arg[maxlen] = save;

}

This doesn’t like the function pointer.

$ cc -c choparg.c

choparg.c:11: Call of non-function

So, uh, what is the obvious thing I am missing? How am I supposed to be passing function pointers in the C compiler that comes with v7?
