Hi Everyone,
I was reading some FreeBSD source code and I found some difficulties with
the function declaration style. Could someone explain me what
char **(*fn) __P((kvm_t *, const struct kinfo_proc *, int));
line in this function declaration exactly means:
static char *
fmt(fn, ki, comm, maxlen)
char **(*fn) __P((kvm_t *, const struct kinfo_proc *, int));
KINFO *ki;
char *comm;
int maxlen;
{
[.. part of the ps command source ..]
I am able to grasp the general idea but that doesn't satisfy me ;>
Thanks for your time,
Naiden
