Other Alias

SSL_rstate_string

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.
