.. 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 turned on, 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"
SSL_pending - obtain number of readable bytes buffered in an SSL object
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> \& int SSL_pending(const SSL *ssl); .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fISSL_pending() returns the number of bytes which are available inside \fBssl for immediate read.
"NOTES"
Header "NOTES" Data are received in blocks from the peer. Therefore data can be buffered inside ssl and are ready for immediate retrieval with \fISSL_read\|(3).
"RETURN VALUES"
Header "RETURN VALUES" The number of bytes pending is returned.
"BUGS"
Header "BUGS" \fISSL_pending() takes into account only bytes from the \s-1TLS/SSL\s0 record that is currently being processed (if any). If the \s-1SSL\s0 object's \fIread_ahead flag is set, additional protocol bytes may have been read containing more \s-1TLS/SSL\s0 records; these are ignored by \fISSL_pending().

Up to OpenSSL 0.9.6, SSL_pending() does not check if the record type of pending data is application data.
