133 .\" For nroff, turn off justification. Always turn off hyphenation; it makes
134 .\" way too many mistakes in technical documents.
138 SSL_rstate_string, SSL_rstate_string_long \- get textual description of state of an SSL object during read operation
140 .IX Header "SYNOPSIS"
142 \& #include <openssl/ssl.h>
144 \& const char *SSL_rstate_string(SSL *ssl);
145 \& const char *SSL_rstate_string_long(SSL *ssl);
148 .IX Header "DESCRIPTION"
149 \&\fISSL_rstate_string()\fR returns a 2 letter string indicating the current read state
150 of the \s-1SSL\s0 object \fBssl\fR.
152 \&\fISSL_rstate_string_long()\fR returns a string indicating the current read state of
153 the \s-1SSL\s0 object \fBssl\fR.
156 When performing a read operation, the \s-1SSL/TLS\s0 engine must parse the record,
157 consisting of header and body. When working in a blocking environment,
158 SSL_rstate_string[_long]() should always return \*(L"\s-1RD\*(R"/\s0\*(L"read done\*(R".
160 This function should only seldom be needed in applications.
162 .IX Header "RETURN VALUES"
163 \&\fISSL_rstate_string()\fR and \fISSL_rstate_string_long()\fR can return the following
165 .ie n .IP """\s-1RH""/\s0""read header""" 4
166 .el .IP "``\s-1RH''/\s0``read header''" 4
167 .IX Item "RH/read header"
168 The header of the record is being evaluated.
169 .ie n .IP """\s-1RB""/\s0""read body""" 4
170 .el .IP "``\s-1RB''/\s0``read body''" 4
171 .IX Item "RB/read body"
172 The body of the record is being evaluated.
173 .ie n .IP """\s-1RD""/\s0""read done""" 4
174 .el .IP "``\s-1RD''/\s0``read done''" 4
175 .IX Item "RD/read done"
176 The record has been completely processed.
177 .ie n .IP """unknown""/""unknown""" 4
178 .el .IP "``unknown''/``unknown''" 4
179 .IX Item "unknown/unknown"
180 The read state is unknown. This should never happen.
