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?
