◆ null_flag

int16_t StringBuffer::null_flag

Buffer currently represents "NULL" (not the empty string!)

◆ synced

int16_t StringBuffer::synced

If this entry is part of the last/current generation array, this flag is GNUNET_YES if the last and current generation are identical (and thus copying is unnecessary if the value didn't change).

This is used in an optimization that improves performance by about 1% — if we use int16_t here. With just "int" for both flags, performance drops (on my system) significantly, most likely due to increased cache misses.
