gnutls_record_recv_packet(3) gnutls gnutls_record_recv_packet(3)

NAME

gnutls_record_recv_packet - API function

SYNOPSIS

#include <gnutls/gnutls.h>
ssize_t gnutls_record_recv_packet(gnutls_session_t session, gnutls_packet_t * packet);

ARGUMENTS

gnutls_session_t session
is a gnutls_session_t type.
gnutls_packet_t * packet
the structure that will hold the packet data

DESCRIPTION

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

3.3.5
