14*2175Sjp161948=head1 DESCRIPTION
15*2175Sjp161948
16*2175Sjp161948SSL_state_string() returns a 6 letter string indicating the current state
17*2175Sjp161948of the SSL object B<ssl>.
18*2175Sjp161948
19*2175Sjp161948SSL_state_string_long() returns a string indicating the current state of
20*2175Sjp161948the SSL object B<ssl>.

22*2175Sjp161948=head1 NOTES
23*2175Sjp161948
24*2175Sjp161948During its use, an SSL objects passes several states. The state is internally
25*2175Sjp161948maintained. Querying the state information is not very informative before
26*2175Sjp161948or when a connection has been established. It however can be of significant
27*2175Sjp161948interest during the handshake.
28*2175Sjp161948
29*2175Sjp161948When using non-blocking sockets, the function call performing the handshake
30*2175Sjp161948may return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition,
31*2175Sjp161948so that SSL_state_string[_long]() may be called.
32*2175Sjp161948
33*2175Sjp161948For both blocking or non-blocking sockets, the details state information
34*2175Sjp161948can be used within the info_callback function set with the
35*2175Sjp161948SSL_set_info_callback() call.
