SSLconnect(3) OpenSSL SSLconnect(3)

NAME
       SSLconnect - initiate the TLS/SSL handshake with an TLS/SSL server

SYNOPSIS
        #include 

        int SSLconnect(SSL *ssl);

DESCRIPTION
       SSLconnect() initiates the TLS/SSL handshake with a server. The
       communication channel must already have been set and assigned to the
       ssssll by setting an underlying BBIIOO.

NNOOTTEESS
       The behaviour of SSLconnect() depends on the underlying BIO.

       If the underlying BIO is bblloocckkiinngg, SSLconnect() will only return once
       the handshake has been finished or an error occurred.

       If the underlying BIO is nnoonn-bblloocckkiinngg, SSLconnect() will also return
       when the underlying BIO could not satisfy the needs of SSLconnect() to
       continue the handshake, indicating the problem by the return value -1.
       In this case a call to SSLgeterror() with the return value of
       SSLconnect() will yield SSSSLLEERRRROORRWWAANNTTRREEAADD or SSSSLLEERRRROORRWWAANNTTWWRRIITTEE.
       The calling process then must repeat the call after taking appropriate
       action to satisfy the needs of SSLconnect().  The action depends on
       the underlying BIO. When using a non-blocking socket, nothing is to be
       done, but select() can be used to check for the required condition.
       When using a buffering BIO, like a BIO pair, data must be written into
       or retrieved out of the BIO before being able to continue.

RETURN VALUES
       The following return values can occur:

       1.  The TLS/SSL handshake was successfully completed, a TLS/SSL
           connection has been established.

       2.  The TLS/SSL handshake was not successful but was shut down
           controlled and by the specifications of the TLS/SSL protocol. Call
           SSLgeterror() with the return value rreett to find out the reason.

       3.  <0

           The TLS/SSL handshake was not successful, because a fatal error
           occurred either at the protocol level or a connection failure
           occurred. The shutdown was not clean. It can also occur of action
           is need to continue the operation for non-blocking BIOs. Call
           SSLgeterror() with the return value rreett to find out the reason.
