gnutls_record_recv_seq(3) gnutls gnutls_record_recv_seq(3)
NAME
gnutls_record_recv_seq - API function
SYNOPSIS
#include <gnutls/gnutls.h>
gnutls_record_recv_seq(3) session, void * data,
size_t data_size, unsigned char * seq);
ARGUMENTS
gnutls_session_t session
is a gnutls_session_t type.
void * data the buffer that the data will be read into
size_t data_size
the number of requested bytes
unsigned char * seq
is the packet's 64-bit sequence number. Should have space
for 8 bytes.
DESCRIPTION
This function is the same as gnutls_record_recv(), except that it
returns in addition to data, the sequence number of the data. This is
useful in DTLS where record packets might be received out-of-order. The
returned 8-byte sequence number is an integer in big-endian format and
should be treated as a unique message identification.
RETURNS
The number of bytes received and zero on EOF. A negative error code is
returned in case of an error. The number of bytes received might be
less than data_size .
SINCE
3.0
