Overview
This is a lower-level function than gnutls_record_recv() and allows to directly receive the whole decrypted packet. That avoids a memory copy, and is intended to be used by applications seeking high performance.
The received packet is accessed using gnutls_packet_get() and must be deinitialized using gnutls_packet_deinit(). The returned packet will be NULL if the return value is zero (EOF).
Returns
The number of bytes received and zero on EOF (for stream connections). A negative error code is returned in case of an error.
Since
