- .SH NAME
- SSL_rstate_string, SSL_rstate_string_long \- get textual description of state of an SSL object during read operation
- .SH SYNOPSIS
- .IX Header "SYNOPSIS"
- .Vb 1
- \& #include <openssl/ssl.h>
- \&
- \& const char *SSL_rstate_string(SSL *ssl);
- \& const char *SSL_rstate_string_long(SSL *ssl);
- .Ve
- .SH DESCRIPTION
- .IX Header "DESCRIPTION"
- \&\fBSSL_rstate_string()\fR returns a 2 letter string indicating the current read state
- of the SSL object \fBssl\fR.
- .PP
- \&\fBSSL_rstate_string_long()\fR returns a string indicating the current read state of
- the SSL object \fBssl\fR.
- .SH NOTES
- .IX Header "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".
- .PP
- This function should only seldom be needed in applications.
- .SH "RETURN VALUES"
- .IX Header "RETURN VALUES"
- \&\fBSSL_rstate_string()\fR and \fBSSL_rstate_string_long()\fR can return the following
- values:
- .IP """RH""/""read header""" 4
- .IX Item """RH""/""read header"""
- The header of the record is being evaluated.
- .IP """RB""/""read body""" 4
- .IX Item """RB""/""read body"""
- The body of the record is being evaluated.
- .IP """unknown""/""unknown""" 4
- .IX Item """unknown""/""unknown"""
- The read state is unknown. This should never happen.
- .PP
- When used with QUIC SSL objects, these functions always return "RH"/"read
- header" in normal conditions.
