I am having trouble seeing how these two functions are accomplshinig the
same thing, checking for control files in the spool.
These files always start with cf.
in lpd.c
makes sense to me.
/*
* Make sure there's some work to do before forking off a child
* XXX - could be common w/ lpq
*/
static int
ckqueue(char *cap)
{
struct dirent *d;
DIR *dirp;
char *spooldir;
if (cgetstr(cap, "sd", &spooldir) >= 0) {
dirp = opendir(spooldir);
free(spooldir);
} else
dirp = opendir(_PATH_DEFSPOOL);
if (dirp == NULL)
return (-1);
while ((d = readdir(dirp)) != NULL) {
if (d->d_name[0] == 'c' && d->d_name[1] == 'f') {
closedir(dirp);
return (1); /* found a cf file */
}
}
closedir(dirp);
return (0);
}
in lpq.c
does not make sense to me
/* XXX - could be common w/ lpd */
static int
ckqueue(char *cap)
{
struct dirent *d;
DIR *dirp;
char *spooldir;
if (cgetstr(cap, "sd", &spooldir) >= 0) {
dirp = opendir(spooldir);
free(spooldir);
} else
dirp = opendir(_PATH_DEFSPOOL);
if (dirp == NULL)
return (-1);
while ((d = readdir(dirp)) != NULL) {
if (d->d_name[0] != 'c' || d->d_name[1] != 'f')
continue; /* daemon control files only */
closedir(dirp);
return (1); /* found something */
}
closedir(dirp);
return (0);
}
the line:
if (d->d_name[0] != 'c' || d->d_name[1] != 'f')
is excluding files that start with cf, yet then has the comment that daemon
controls files are found.
They both acccomplish the same thing of returning if there are files in the
spool.
Thanks,
