  153. \&\fBSSL_state_string()\fR returns an abbreviated string indicating the current state

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