cvs commit: apache-2.0/src/include ap_buckets.h
fanf 00/09/03 22:42:20
Modified: src/ap ap_buckets.c ap_buckets_heap.c ap_buckets_pipe.c
src/include ap_buckets.h
Log:
avoid a copy in the pipe bucket read code
and make the length return argument in ap_bucket_create_heap optional
(which is only really true when not copying)
