143 SSL_pending \- obtain number of readable bytes buffered in an SSL object
147 .IX Header "SYNOPSIS"
149 \& #include <openssl/ssl.h>
151 \& int SSL_pending(const SSL *ssl);
154 .IX Header "DESCRIPTION"
155 \&\fISSL_pending()\fR returns the number of bytes which are available inside
156 \&\fBssl\fR for immediate read.
159 Data are received in blocks from the peer. Therefore data can be buffered
160 inside \fBssl\fR and are ready for immediate retrieval with
161 \&\fISSL_read\fR\|(3).
163 .IX Header "RETURN VALUES"
164 The number of bytes pending is returned.
167 \&\fISSL_pending()\fR takes into account only bytes from the \s-1TLS/SSL\s0 record
168 that is currently being processed (if any). If the \fB\s-1SSL\s0\fR object's
169 \&\fIread_ahead\fR flag is set, additional protocol bytes may have been
170 read containing more \s-1TLS/SSL\s0 records; these are ignored by
171 \&\fISSL_pending()\fR.
173 Up to OpenSSL 0.9.6, \fISSL_pending()\fR does not check if the record type
174 of pending data is application data.
