131 .IX Title "SSL_pending 3"
132 .TH SSL_pending 3 "2007-03-28" "0.9.8e" "OpenSSL"
134 SSL_pending \- obtain number of readable bytes buffered in an SSL object
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/ssl.h>
142 \& int SSL_pending(const SSL *ssl);
145 .IX Header "DESCRIPTION"
146 \&\fISSL_pending()\fR returns the number of bytes which are available inside
147 \&\fBssl\fR for immediate read.
150 Data are received in blocks from the peer. Therefore data can be buffered
151 inside \fBssl\fR and are ready for immediate retrieval with
152 \&\fISSL_read\fR\|(3).
154 .IX Header "RETURN VALUES"
155 The number of bytes pending is returned.
158 \&\fISSL_pending()\fR takes into account only bytes from the \s-1TLS/SSL\s0 record
159 that is currently being processed (if any). If the \fB\s-1SSL\s0\fR object's
160 \&\fIread_ahead\fR flag is set, additional protocol bytes may have been
161 read containing more \s-1TLS/SSL\s0 records; these are ignored by
162 \&\fISSL_pending()\fR.
164 Up to OpenSSL 0.9.6, \fISSL_pending()\fR does not check if the record type
165 of pending data is application data.
