gnutls_record_send2 - API function

NAME SYNOPSIS ARGUMENTS DESCRIPTION RETURNS SINCE REPORTING BUGS COPYRIGHT SEE ALSO

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

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().
