SSL_PENDING(3) BSD Library Functions Manual SSL_PENDING(3)NAME
SSL_pending — obtain number of readable bytes buffered in an SSL object
SYNOPSIS
#include <openssl/ssl.h>
int
SSL_pending(const SSL *ssl);
DESCRIPTIONSSL_pending() returns the number of bytes which are available inside ssl
for immediate read.
NOTES
Data are received in blocks from the peer. Therefore data can be
buffered inside ssl and are ready for immediate retrieval with
SSL_read(3).
RETURN VALUES
The number of bytes pending is returned.
SEE ALSOssl(3), SSL_read(3)BUGSSSL_pending() takes into account only bytes from the TLS/SSL record that
is currently being processed (if any). If the SSL object's read_ahead
flag is set, additional protocol bytes may have been read containing more
TLS/SSL records; these are ignored by SSL_pending().
Up to OpenSSL 0.9.6, SSL_pending() does not check if the record type of
pending data is application data.
