.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fISSL_rstate_string()\fR returns a 2 letter string indicating the current read state
of the \s-1SSL\s0 object \fBssl\fR.
.PP
\&\fISSL_rstate_string_long()\fR returns a string indicating the current read state of
the \s-1SSL\s0 object \fBssl\fR.
.SH "NOTES"
.IX Header "NOTES"
When performing a read operation, the \s-1SSL/TLS\s0 engine must parse the record,
consisting of header and body. When working in a blocking environment,
SSL_rstate_string[_long]() should always return \*(L"\s-1RD\s0\*(R"/\*(L"read done\*(R".
.PP
This function should only seldom be needed in applications.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fISSL_rstate_string()\fR and \fISSL_rstate_string_long()\fR can return the following
values:
.ie n .IP """\s-1RH\s0""/""read header""" 4
.el .IP "``\s-1RH\s0''/``read header''" 4
.IX Item "RH/read header"
The header of the record is being evaluated.
.ie n .IP """\s-1RB\s0""/""read body""" 4
.el .IP "``\s-1RB\s0''/``read body''" 4
.IX Item "RB/read body"
The body of the record is being evaluated.
.ie n .IP """\s-1RD\s0""/""read done""" 4
.el .IP "``\s-1RD\s0''/``read done''" 4
.IX Item "RD/read done"
The record has been completely processed.
.ie n .IP """unknown""/""unknown""" 4
.el .IP "``unknown''/``unknown''" 4
.IX Item "unknown/unknown"
The read state is unknown. This should never happen.
