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