=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(const SSL *ssl);
|
|
const char *SSL_state_string_long(const 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.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
Detailed description of possible states to be included later.
