Имя (Name)
gnutls_record_recv_seq - API function
Синопсис (Synopsis)
#include <gnutls/gnutls.h>
ssize_t gnutls_record_recv_seq(gnutls_session_t session, void *
data, size_t data_size, unsigned char * seq);
Аргументы (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.
Описание (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.
Возвращаемое значение (Return value)
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 .
