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
