SSL_rstate_string(3)



NAME

SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation


SYNOPSIS

 #include <openssl/ssl.h>
 const char *SSL_rstate_string(SSL *ssl);
 const char *SSL_rstate_string_long(SSL *ssl);


DESCRIPTION

SSL_rstate_string() returns a 2 letter string indicating the current read state of the SSL object ssl.

SSL_rstate_string_long() returns a string indicating the current read state of the SSL object ssl.


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.


RETURN VALUES

SSL_rstate_string() and SSL_rstate_string_long() can return the following values:

"RH"/"read header"

The header of the record is being evaluated.

"RB"/"read body"

The body of the record is being evaluated.

"RD"/"read done"

The record has been completely processed.

"unknown"/"unknown"

The read state is unknown. This should never happen.
