NAME
gnutls_record_send2 - API function
SYNOPSIS
#include <gnutls/gnutls.h>
ssize_t gnutls_record_send2(gnutls_session_t session, const void
* data, size_t data_size, size_t pad, unsigned flags);
ARGUMENTS
gnutls_session_t session
is a gnutls_session_t type.
const void * data
contains the data to send
size_t data_size
is the length of the data
size_t pad padding to be added to the record
unsigned flags
must be zero
DESCRIPTION
This function is identical to gnutls_record_send() except that it
takes an extra argument to specify padding to be added the
record. To determine the maximum size of padding, use
gnutls_record_get_max_size() and gnutls_record_overhead_size().
Note that in order for GnuTLS to provide constant time processing
of padding and data in TLS1.3, the flag GNUTLS_SAFE_PADDING_CHECK
must be used in gnutls_init().
RETURNS
The number of bytes sent, or a negative error code. The number
of bytes sent might be less than data_size . The maximum number
of bytes this function can send in a single call depends on the
negotiated maximum record size.
SINCE
3.6.3
