NAME¶
gnutls_record_recv_seq - API function
SYNOPSIS¶
#include <gnutls/gnutls.h>
ssize_t gnutls_record_recv_seq(gnutls_session_t session, void *
data, size_t data_size, unsigned char *
seq);
ARGUMENTS¶
- gnutls_session_t session
- is a gnutls_session_t structure.
- 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 .
