150 \&\fIX509_NAME_print_ex()\fR prints a human readable version of \fBnm\fR to \s-1BIO\s0 \fBout\fR. Each
151 line (for multiline formats) is indented by \fBindent\fR spaces. The output format
152 can be extensively customised by use of the \fBflags\fR parameter.
153 .PP
154 \&\fIX509_NAME_print_ex_fp()\fR is identical to \fIX509_NAME_print_ex()\fR except the output is
155 written to \s-1FILE\s0 pointer \fBfp\fR.
156 .PP
157 \&\fIX509_NAME_oneline()\fR prints an \s-1ASCII\s0 version of \fBa\fR to \fBbuf\fR. At most \fBsize\fR
158 bytes will be written. If \fBbuf\fR is \fB\s-1NULL\s0\fR then a buffer is dynamically allocated
159 and returned, otherwise \fBbuf\fR is returned.
160 .PP
161 \&\fIX509_NAME_print()\fR prints out \fBname\fR to \fBbp\fR indenting each line by \fBobase\fR
162 characters. Multiple lines are used if the output (including indent) exceeds
163 80 characters.
164 .SH "NOTES"
165 .IX Header "NOTES"
166 The functions \fIX509_NAME_oneline()\fR and \fIX509_NAME_print()\fR are legacy functions which
167 produce a non standard output form, they don't handle multi character fields and
168 have various quirks and inconsistencies. Their use is strongly discouraged in new
169 applications.
170 .PP
171 Although there are a large number of possible flags for most purposes
172 \&\fB\s-1XN_FLAG_ONELINE\s0\fR, \fB\s-1XN_FLAG_MULTILINE\s0\fR or \fB\s-1XN_FLAG_RFC2253\s0\fR will suffice.
173 As noted on the \fIASN1_STRING_print_ex\fR\|(3) manual page
174 for \s-1UTF8\s0 terminals the \fB\s-1ASN1_STRFLGS_ESC_MSB\s0\fR should be unset: so for example
175 \&\fB\s-1XN_FLAG_ONELINE\s0 & ~ASN1_STRFLGS_ESC_MSB\fR would be used.
176 .PP
177 The complete set of the flags supported by \fIX509_NAME_print_ex()\fR is listed below.
178 .PP
179 Several options can be ored together.
180 .PP
181 The options \fB\s-1XN_FLAG_SEP_COMMA_PLUS\s0\fR, \fB\s-1XN_FLAG_SEP_CPLUS_SPC\s0\fR,
182 \&\fB\s-1XN_FLAG_SEP_SPLUS_SPC\s0\fR and \fB\s-1XN_FLAG_SEP_MULTILINE\s0\fR determine the field separators
183 to use. Two distinct separators are used between distinct RelativeDistinguishedName
184 components and separate values in the same \s-1RDN\s0 for a multi-valued \s-1RDN\s0. Multi-valued
185 RDNs are currently very rare so the second separator will hardly ever be used.
186 .PP
187 \&\fB\s-1XN_FLAG_SEP_COMMA_PLUS\s0\fR uses comma and plus as separators. \fB\s-1XN_FLAG_SEP_CPLUS_SPC\s0\fR
188 uses comma and plus with spaces: this is more readable that plain comma and plus.
189 \&\fB\s-1XN_FLAG_SEP_SPLUS_SPC\s0\fR uses spaced semicolon and plus. \fB\s-1XN_FLAG_SEP_MULTILINE\s0\fR uses
190 spaced newline and plus respectively.
191 .PP
192 If \fB\s-1XN_FLAG_DN_REV\s0\fR is set the whole \s-1DN\s0 is printed in reversed order.
193 .PP
194 The fields \fB\s-1XN_FLAG_FN_SN\s0\fR, \fB\s-1XN_FLAG_FN_LN\s0\fR, \fB\s-1XN_FLAG_FN_OID\s0\fR,
195 \&\fB\s-1XN_FLAG_FN_NONE\s0\fR determine how a field name is displayed. It will
196 use the short name (e.g. \s-1CN\s0) the long name (e.g. commonName) always
197 use \s-1OID\s0 numerical form (normally OIDs are only used if the field name is not
198 recognised) and no field name respectively.
199 .PP
200 If \fB\s-1XN_FLAG_SPC_EQ\s0\fR is set then spaces will be placed around the '=' character
201 separating field names and values.
202 .PP
203 If \fB\s-1XN_FLAG_DUMP_UNKNOWN_FIELDS\s0\fR is set then the encoding of unknown fields is
204 printed instead of the values.
205 .PP
206 If \fB\s-1XN_FLAG_FN_ALIGN\s0\fR is set then field names are padded to 20 characters: this
207 is only of use for multiline format.
208 .PP
209 Additionally all the options supported by \fIASN1_STRING_print_ex()\fR can be used to
210 control how each field value is displayed.
211 .PP
212 In addition a number options can be set for commonly used formats.
213 .PP
214 \&\fB\s-1XN_FLAG_RFC2253\s0\fR sets options which produce an output compatible with \s-1RFC2253\s0 it
215 is equivalent to:
216 \fB\s-1ASN1_STRFLGS_RFC2253\s0 | \s-1XN_FLAG_SEP_COMMA_PLUS\s0 | \s-1XN_FLAG_DN_REV\s0 | \s-1XN_FLAG_FN_SN\s0 | \s-1XN_FLAG_DUMP_UNKNOWN_FIELDS\s0\fR
217 .PP
218 \&\fB\s-1XN_FLAG_ONELINE\s0\fR is a more readable one line format which is the same as:
219 \fB\s-1ASN1_STRFLGS_RFC2253\s0 | \s-1ASN1_STRFLGS_ESC_QUOTE\s0 | \s-1XN_FLAG_SEP_CPLUS_SPC\s0 | \s-1XN_FLAG_SPC_EQ\s0 | \s-1XN_FLAG_FN_SN\s0\fR
220 .PP
221 \&\fB\s-1XN_FLAG_MULTILINE\s0\fR is a multiline format which is the same as:
222 \fB\s-1ASN1_STRFLGS_ESC_CTRL\s0 | \s-1ASN1_STRFLGS_ESC_MSB\s0 | \s-1XN_FLAG_SEP_MULTILINE\s0 | \s-1XN_FLAG_SPC_EQ\s0 | \s-1XN_FLAG_FN_LN\s0 | \s-1XN_FLAG_FN_ALIGN\s0\fR
223 .PP
224 \&\fB\s-1XN_FLAG_COMPAT\s0\fR uses a format identical to \fIX509_NAME_print()\fR: in fact it calls \fIX509_NAME_print()\fR internally.
