4
5SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation
6
7=head1 SYNOPSIS
8
9 #include <openssl/ssl.h>
10
11 const char *SSL_rstate_string(SSL *ssl);
12 const char *SSL_rstate_string_long(SSL *ssl);
13
14=head1 DESCRIPTION
15
16SSL_rstate_string() returns a 2 letter string indicating the current read state
17of the SSL object B<ssl>.
18
19SSL_rstate_string_long() returns a string indicating the current read state of
20the SSL object B<ssl>.
21
22=head1 NOTES
23
24When performing a read operation, the SSL/TLS engine must parse the record,
25consisting of header and body. When working in a blocking environment,
26SSL_rstate_string[_long]() should always return "RD"/"read done".
27
28This function should only seldom be needed in applications.
29
30=head1 RETURN VALUES
31
32SSL_rstate_string() and SSL_rstate_string_long() can return the following
33values:
34
35=over 4
36
37=item "RH"/"read header"
38
39The header of the record is being evaluated.
40

42
43The body of the record is being evaluated.
44
45=item "RD"/"read done"
46
