|  | =head1 NAME | 
|  |  | 
|  | SSL_state_string, SSL_state_string_long - get textual description of state of an SSL object | 
|  |  | 
|  | =head1 SYNOPSIS | 
|  |  | 
|  | #include <openssl/ssl.h> | 
|  |  | 
|  | const char *SSL_state_string(SSL *ssl); | 
|  | const char *SSL_state_string_long(SSL *ssl); | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | SSL_state_string() returns a 6 letter string indicating the current state | 
|  | of the SSL object B<ssl>. | 
|  |  | 
|  | SSL_state_string_long() returns a string indicating the current state of | 
|  | the SSL object B<ssl>. | 
|  |  | 
|  | =head1 NOTES | 
|  |  | 
|  | During its use, an SSL 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. | 
|  |  | 
|  | When using non-blocking sockets, the function call performing the handshake | 
|  | may return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition, | 
|  | so that SSL_state_string[_long]() may be called. | 
|  |  | 
|  | For both blocking or non-blocking sockets, the details state information | 
|  | can be used within the info_callback function set with the | 
|  | SSL_set_info_callback() call. | 
|  |  |

|  | Detailed description of possible states to be included later. |
