+.SH NAME
+BIO_f_readbuffer
+\&\- read only buffering BIO that supports BIO_tell() and BIO_seek()
+.SH SYNOPSIS
+.IX Header "SYNOPSIS"
+.Vb 1
+\& #include <openssl/bio.h>
+\&
+\& const BIO_METHOD *BIO_f_readbuffer(void);
+.Ve
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBBIO_f_readbuffer()\fR returns the read buffering BIO method.
+.PP
+This BIO filter can be inserted on top of BIO's that do not support \fBBIO_tell()\fR
+or \fBBIO_seek()\fR (e.g. A file BIO that uses stdin).
+.PP
+Data read from a read buffering BIO comes from an internal buffer which is
+filled from the next BIO in the chain.
+.PP
+\&\fBBIO_gets()\fR is supported for read buffering BIOs.
+Writing data to a read buffering BIO is not supported.
+.PP
+Calling \fBBIO_reset()\fR on a read buffering BIO does not clear any buffered data.
+.SH NOTES
+.IX Header "NOTES"
+Read buffering BIOs implement \fBBIO_read_ex()\fR by using \fBBIO_read_ex()\fR operations
+on the next BIO (e.g. a file BIO) in the chain and storing the result in an
+internal buffer, from which bytes are given back to the caller as appropriate
+for the call. \fBBIO_read_ex()\fR is guaranteed to give the caller the number of bytes
+it asks for, unless there's an error or end of communication is reached in the
+next BIO. The internal buffer can grow to cache the entire contents of the next
+BIO in the chain. \fBBIO_seek()\fR uses the internal buffer, so that it can only seek
+into data that is already read.
