|  | =head1 NAME | 
|  |  | 
|  | SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation | 
|  |  | 
|  | =head1 SYNOPSIS | 
|  |  | 
|  | #include <openssl/ssl.h> | 
|  |  | 
|  | const char *SSL_rstate_string(SSL *ssl); | 
|  | const char *SSL_rstate_string_long(SSL *ssl); | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | SSL_rstate_string() returns a 2 letter string indicating the current read state | 
|  | of the SSL object B<ssl>. | 
|  |  | 
|  | SSL_rstate_string_long() returns a string indicating the current read state of | 
|  | the SSL object B<ssl>. | 
|  |  | 
|  | =head1 NOTES | 
|  |  | 
|  | When performing a read operation, the SSL/TLS engine must parse the record, | 
|  | consisting of header and body. When working in a blocking environment, | 
|  | SSL_rstate_string[_long]() should always return "RD"/"read done". | 
|  |  | 
|  | This function should only seldom be needed in applications. | 
|  |  | 
|  | =head1 RETURN VALUES | 
|  |  | 
|  | SSL_rstate_string() and SSL_rstate_string_long() can return the following | 
|  | values: | 
|  |  | 
|  | =over 4 | 
|  |  | 
|  | =item "RH"/"read header" | 
|  |  | 
|  | The header of the record is being evaluated. | 
|  |  | 
|  | =item "RB"/"read body" | 
|  |  | 
|  | The body of the record is being evaluated. | 
|  |  | 
|  | =item "RD"/"read done" | 
|  |  | 
|  | The record has been completely processed. | 
|  |  | 
|  | =item "unknown"/"unknown" | 
|  |  | 
|  | The read state is unknown. This should never happen. |
