Description Enji Cooper freebsd_committer 2014-07-30 04:58:49 UTC
The LIST section example notes np_temp, but implies np_temp's existence in the {SLIST,STAILQ,TAILQ} sections.

Hi --

Is this ticket still valid? I've compared what's on sys/queue.h with queue.3 and did not find the discrepancies noted by the user.

queue.h defines these functions:

#define SLIST_FOREACH_SAFE(var, head, field, tvar)                      \
#define SLIST_FOREACH_FROM_SAFE(var, head, field, tvar)                 \
#define STAILQ_FOREACH_SAFE(var, head, field, tvar)                     \
#define STAILQ_FOREACH_FROM_SAFE(var, head, field, tvar)                \
#define LIST_FOREACH_SAFE(var, head, field, tvar)                       \
#define LIST_FOREACH_FROM_SAFE(var, head, field, tvar)                  \
#define TAILQ_FOREACH_SAFE(var, head, field, tvar)                      \
#define TAILQ_FOREACH_FROM_SAFE(var, head, field, tvar)                 \
#define TAILQ_FOREACH_REVERSE_SAFE(var, head, headname, field, tvar)    \
#define TAILQ_FOREACH_REVERSE_FROM_SAFE(var, head, headname, field, tvar) \

Every example on queue.3 that uses these functions do make a reference to tvar (declared as np_temp on the man page).

SLIST_FOREACH_SAFE(np, &head, entries, np_temp) {
STAILQ_FOREACH_SAFE(np, &head, entries, np_temp) {
LIST_FOREACH_SAFE(np, &head, entries, np_temp) {
TAILQ_FOREACH_SAFE(np, &head, entries, np_temp) {

Did I miss anything ?

See bug #192267 and attachment #227599 [details].
The attachment there changes np_temp to tvar to match the macro argument name.
