SSL_rstate_string(3ssl)
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.
