9*2175Sjp161948 #include <openssl/ssl.h>
10*2175Sjp161948
11*2175Sjp161948 const char *SSL_rstate_string(SSL *ssl);

14*2175Sjp161948=head1 DESCRIPTION
15*2175Sjp161948
16*2175Sjp161948SSL_rstate_string() returns a 2 letter string indicating the current read state
17*2175Sjp161948of the SSL object B<ssl>.
18*2175Sjp161948
19*2175Sjp161948SSL_rstate_string_long() returns a string indicating the current read state of
20*2175Sjp161948the SSL object B<ssl>.
21*2175Sjp161948
22*2175Sjp161948=head1 NOTES
23*2175Sjp161948
24*2175Sjp161948When performing a read operation, the SSL/TLS engine must parse the record,
25*2175Sjp161948consisting of header and body. When working in a blocking environment,
26*2175Sjp161948SSL_rstate_string[_long]() should always return "RD"/"read done".
27*2175Sjp161948
28*2175Sjp161948This function should only seldom be needed in applications.

30*2175Sjp161948=head1 RETURN VALUES
31*2175Sjp161948
32*2175Sjp161948SSL_rstate_string() and SSL_rstate_string_long() can return the following
33*2175Sjp161948values:
34*2175Sjp161948
35*2175Sjp161948=over 4
36*2175Sjp161948
37*2175Sjp161948=item "RH"/"read header"
38*2175Sjp161948
39*2175Sjp161948The header of the record is being evaluated.
40*2175Sjp161948
41*2175Sjp161948=item "RB"/"read body"
42*2175Sjp161948
43*2175Sjp161948The body of the record is being evaluated.
44*2175Sjp161948
45*2175Sjp161948=item "RD"/"read done"
46*2175Sjp161948
47*2175Sjp161948The record has been completely processed.
48*2175Sjp161948
49*2175Sjp161948=item "unknown"/"unknown"
50*2175Sjp161948
51*2175Sjp161948The read state is unknown. This should never happen.
