of the \s-1SSL\s0 object \fBssl\fR.

\&\fISSL_state_string_long()\fR returns a string indicating the current state of
the \s-1SSL\s0 object \fBssl\fR.
.SH "NOTES"
.IX Header "NOTES"
During its use, an \s-1SSL\s0 objects passes several states. The state is internally
maintained. Querying the state information is not very informative before
or when a connection has been established. It however can be of significant
interest during the handshake.
.PP
When using non-blocking sockets, the function call performing the handshake
may return with \s-1SSL_ERROR_WANT_READ\s0 or \s-1SSL_ERROR_WANT_WRITE\s0 condition,
so that SSL_state_string[_long]() may be called.
.PP
For both blocking or non-blocking sockets, the details state information
can be used within the info_callback function set with the
\&\fISSL_set_info_callback()\fR call.
