.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
DTLS_get_data_mtu - Get maximum data payload size
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> \& size_t DTLS_get_data_mtu(const SSL *ssl); .Ve
"DESCRIPTION"
Header "DESCRIPTION" This function obtains the maximum data payload size for the established \s-1DTLS\s0 connection ssl, based on the \s-1DTLS\s0 record \s-1MTU\s0 and the overhead of the \s-1DTLS\s0 record header, encryption and authentication currently in use.
"RETURN VALUES"
Header "RETURN VALUES" Returns the maximum data payload size on success, or 0 on failure.
"HISTORY"
Header "HISTORY" The DTLS_get_data_mtu() function was added in OpenSSL 1.1.1.
