.SH "NAME"
SSL_pending \- obtain number of readable bytes buffered in an SSL object
.SH "SYNOPSIS"
.PP
.Vb 1
\& #include <openssl/ssl.h>
.Ve
.Vb 1
\& int SSL_pending(SSL *ssl);
.Ve
.SH "DESCRIPTION"
\fISSL_pending()\fR returns the number of bytes which are available inside
\fBssl\fR for immediate read.
.SH "NOTES"
Data are received in blocks from the peer. Therefore data can be buffered
inside \fBssl\fR and are ready for immediate retrieval with
SSL_read(3).
.SH "RETURN VALUES"
The number of bytes pending is returned.
.SH "BUGS"
\fISSL_pending()\fR takes into account only bytes from the TLS/SSL record
that is currently being processed (if any).  If the \fBSSL\fR object's
\fIread_ahead\fR flag is set, additional protocol bytes may have been
read containing more TLS/SSL records; these are ignored by
\fISSL_pending()\fR.
.PP
Up to OpenSSL 0.9.6, \fISSL_pending()\fR does not check if the record type
of pending data is application data.
