128 .\" For nroff, turn off justification. Always turn off hyphenation; it makes

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