In this case i need to reserve some value for "err" as success, because both 0 and negative values are passed to caller when this function returns false(check failed). May be i will inline this function. > Its not very clear (only for me perhaps) how > dequeue_total and len correlate. Are they > equal here?

When "dequeued_total > 0" record copy is succeed. "len" is length of user buffer. I think i can replace "dequeued_total" to some flag, like "error", because in SOCK_SEQPACKET mode record could be copied whole or error returned.
