  2. =head1 NAME
  3. SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation
  4. =head1 SYNOPSIS
  5. #include <openssl/ssl.h>
  6. const char *SSL_rstate_string(SSL *ssl);
  7. const char *SSL_rstate_string_long(SSL *ssl);
  8. =head1 DESCRIPTION
  9. SSL_rstate_string() returns a 2 letter string indicating the current read state
  10. of the SSL object B<ssl>.
  11. SSL_rstate_string_long() returns a string indicating the current read state of
  12. the SSL object B<ssl>.
  13. =head1 NOTES
  14. When performing a read operation, the SSL/TLS engine must parse the record,
  15. consisting of header and body. When working in a blocking environment,
  16. SSL_rstate_string[_long]() should always return "RD"/"read done".
  17. This function should only seldom be needed in applications.
  18. =head1 RETURN VALUES
  19. SSL_rstate_string() and SSL_rstate_string_long() can return the following
  20. values:
  21. =over 4
  22. =item "RH"/"read header"
  23. The header of the record is being evaluated.
  24. =item "RB"/"read body"
  25. The body of the record is being evaluated.
  26. =item "RD"/"read done"
  27. The record has been completely processed.
  28. =item "unknown"/"unknown"
  29. The read state is unknown. This should never happen.
