Well, they are probably legitimate warnings, they're just new
compared to the previous compiler. Also note that I'm running
with CWARNFLAGS set pretty close to BDECFLAGS.
When compiling lpr/common_source/ctlinfo.c, there's a code
fragment of:
void
ctl_freeinf(struct cjobinfo *cjinf)
{
struct cjprivate *cpriv;
cpriv = cjinf->cji_priv;
if ((cpriv == NULL) || (cpriv != cpriv->pub.cji_priv)) {
syslog(LOG_ERR, "in ctl_freeinf(%p): invalid cjinf (cpriv %p)",
cjinf, cpriv);
return;
}
}
|_ ../ctlinfo.c:231: warning: void format, cjobinfo arg (arg 3)
|_ ../ctlinfo.c:231: warning: void format, cjprivate arg (arg 4)
Apparently it wants %p to be used with (void *) or (char *), and not
(struct blahblah *). If I cast those parameters to (void *) then the
warning goes away. Is that a change I should make? Why does it care
what it's a pointer to, as long as it's a pointer to data?
Also, in lpr/common_source/net.c, there's a code fragment of:
do {
cp = va_arg(ap, char *);
n++;
} while (cp);
where the call to va_arg generates 10 warnings of:
|_ ../net.c:278: warning: pointer of type `void *' used in arithmetic
Should va_arg() be changed?
None of this is urgent, obviously. I'm just wondering.
