.. 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. | will give a
real vertical bar. \*(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<>

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

For nroff, turn off justification. Always turn off hyphenation; it
makes way too many mistakes in technical documents.

Accent mark definitions (@(#)ms.acc 1.5 88/02/08 SMI; from UCB 4.2).
Fear. Run. Save yourself. No user-serviceable parts.

Title "SSL_pending 3" C SSL_pending - obtain number of readable bytes buffered in an \s-1SSL\s0 object Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> .Ve .Vb 1 int SSL_pending(SSL *ssl); .Ve Header "DESCRIPTION" \fISSL_pending() returns the number of bytes which are available inside \fBssl for immediate read. Header "NOTES" Data are received in blocks from the peer. Therefore data can be buffered inside ssl and are ready for immediate retrieval with SSL_read(3). Header "RETURN VALUES" The number of bytes pending is returned. 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.
