NAME
SSLclear - reset SSL object to allow another connection
SYNOPSIS
#include
int SSLclear(SSL *ssl);DESCRIPTION
Reset ssssll to allow another connection. All settings (method, ciphers, BIOs) are kept. NNOOTTEESS SSLclear is used to prepare an SSL object for a new connection. While all settings are kept, a side effect is the handling of the current SSL session. If a session is still ooppeenn, it is considered bad and will be removed from the session cache, as required by RFC2246. A session is considered open, if SSLshutdown(3) was not called for the connection or at least SSLsetshutdown(3) was used to set the SSLSENTSHUTDOWN state. If a session was closed cleanly, the session object will be kept and all settings corresponding. This explicitly means, that e.g. the special method used during the session will be kept for the next handshake. So if the session was a TLSv1 session, a SSL client object will use a TLSv1 client method for the next handshake and a SSL server object will use a TLSv1 server method, even if SSLv23*methods were chosen on startup. This will might lead to connection failures (see SSLnew(3)) for a description of the method's properties. WWAARRNNIINNGGSS SSLclear() resets the SSL object to allow for another connection. The reset operation however keeps several settings of the last sessions (some of these settings were made automatically during the last handshake). It only makes sense when opening a new session (or reusing an old one) with the same peer that shares these settings. SSLclear() is not a short form for the sequence SSLfree(3); SSLnew(3); .RETURN VALUES
The following return values can occur: 0 The SSLclear() operation could not be performed. Check the error stack to find out the reason. 1 The SSLclear() operation was successful.
