.SH NAME

gnutls_dtls_set_data_mtu \- API function

.SH SYNOPSIS

.B #include <gnutls/dtls.h>

.sp

.BI "int gnutls_dtls_set_data_mtu(gnutls_session_t " session ", unsigned int " mtu ");"

.SH ARGUMENTS

.IP "gnutls_session_t session" 12

is a \fBgnutls_session_t\fP type.

.IP "unsigned int mtu" 12

The maximum unencrypted transfer unit of the session

.SH "DESCRIPTION"

This function will set the maximum size of the *unencrypted* records

which will be sent over a DTLS session. It is equivalent to calculating

the DTLS packet overhead with the current encryption parameters, and

calling \fBgnutls_dtls_set_mtu()\fP with that value. In particular, this means

that you may need to call this function again after any negotiation or

renegotiation, in order to ensure that the MTU is still sufficient to

account for the new protocol overhead.

In most cases you only need to call \fBgnutls_dtls_set_mtu()\fP with

the maximum MTU of your transport layer.

.SH "RETURNS"

\fBGNUTLS_E_SUCCESS\fP (0) on success, or a negative error code.

.SH "SINCE"

3.1
