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.
