1413d40330Schristos=head1 DESCRIPTION
1513d40330Schristos
16*b0d17251SchristosSSL_state_string() returns an abbreviated string indicating the current state
17*b0d17251Schristosof the SSL object B<ssl>. The returned NUL-terminated string contains 6 or fewer characters.
1813d40330Schristos
19*b0d17251SchristosSSL_state_string_long() returns a descriptive string indicating the current state of
2013d40330Schristosthe SSL object B<ssl>.

2213d40330Schristos=head1 NOTES
2313d40330Schristos
2413d40330SchristosDuring its use, an SSL objects passes several states. The state is internally
2513d40330Schristosmaintained. Querying the state information is not very informative before
2613d40330Schristosor when a connection has been established. It however can be of significant
2713d40330Schristosinterest during the handshake.
2813d40330Schristos
29f30e0929SchristosWhen using nonblocking sockets, the function call performing the handshake
3013d40330Schristosmay return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition,
3113d40330Schristosso that SSL_state_string[_long]() may be called.
3213d40330Schristos
33f30e0929SchristosFor both blocking or nonblocking sockets, the details state information
3413d40330Schristoscan be used within the info_callback function set with the
3513d40330SchristosSSL_set_info_callback() call.
