=head1 NAME
|
|
|
|
SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
const char *SSL_rstate_string(SSL *ssl);
|
|
const char *SSL_rstate_string_long(SSL *ssl);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_rstate_string() returns a 2 letter string indicating the current read state
|
|
of the SSL object B<ssl>.
|
|
|
|
SSL_rstate_string_long() returns a string indicating the current read state of
|
|
the SSL object B<ssl>.
|
|
|
|
=head1 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.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_rstate_string() and SSL_rstate_string_long() can return the following
|
|
values:
|
|
|
|
=over 4
|
|
|
|
=item "RH"/"read header"
|
|
|
|
The header of the record is being evaluated.
|
|
|
|
=item "RB"/"read body"
|
|
|
|
The body of the record is being evaluated.
|
|
|
|
=item "unknown"/"unknown"
|
|
|
|
The read state is unknown. This should never happen.
|
|
|
|
=back
|
|
|
|
When used with QUIC SSL objects, these functions always return "RH"/"read
|
|
header" in normal conditions.
