156\&\fIX509_NAME_print_ex()\fR prints a human readable version of \fBnm\fR to \s-1BIO \s0\fBout\fR. Each
157line (for multiline formats) is indented by \fBindent\fR spaces. The output format
158can be extensively customised by use of the \fBflags\fR parameter.
159.PP
160\&\fIX509_NAME_print_ex_fp()\fR is identical to \fIX509_NAME_print_ex()\fR except the output is
161written to \s-1FILE\s0 pointer \fBfp\fR.
162.PP
163\&\fIX509_NAME_oneline()\fR prints an \s-1ASCII\s0 version of \fBa\fR to \fBbuf\fR. At most \fBsize\fR
164bytes will be written. If \fBbuf\fR is \fB\s-1NULL\s0\fR then a buffer is dynamically allocated
165and returned, otherwise \fBbuf\fR is returned.
166.PP
167\&\fIX509_NAME_print()\fR prints out \fBname\fR to \fBbp\fR indenting each line by \fBobase\fR
168characters. Multiple lines are used if the output (including indent) exceeds
16980 characters.
170.SH "NOTES"
171.IX Header "NOTES"
172The functions \fIX509_NAME_oneline()\fR and \fIX509_NAME_print()\fR are legacy functions which
173produce a non standard output form, they don't handle multi character fields and
174have various quirks and inconsistencies. Their use is strongly discouraged in new
175applications.
176.PP
177Although there are a large number of possible flags for most purposes
178\&\fB\s-1XN_FLAG_ONELINE\s0\fR, \fB\s-1XN_FLAG_MULTILINE\s0\fR or \fB\s-1XN_FLAG_RFC2253\s0\fR will suffice.
179As noted on the \fIASN1_STRING_print_ex\fR\|(3) manual page
180for \s-1UTF8\s0 terminals the \fB\s-1ASN1_STRFLGS_ESC_MSB\s0\fR should be unset: so for example
181\&\fB\s-1XN_FLAG_ONELINE &\s0 ~ASN1_STRFLGS_ESC_MSB\fR would be used.
182.PP
183The complete set of the flags supported by \fIX509_NAME_print_ex()\fR is listed below.
184.PP
185Several options can be ored together.
186.PP
187The options \fB\s-1XN_FLAG_SEP_COMMA_PLUS\s0\fR, \fB\s-1XN_FLAG_SEP_CPLUS_SPC\s0\fR,
188\&\fB\s-1XN_FLAG_SEP_SPLUS_SPC\s0\fR and \fB\s-1XN_FLAG_SEP_MULTILINE\s0\fR determine the field separators
189to use. Two distinct separators are used between distinct RelativeDistinguishedName
190components and separate values in the same \s-1RDN\s0 for a multi-valued \s-1RDN.\s0 Multi-valued
191RDNs are currently very rare so the second separator will hardly ever be used.
192.PP
193\&\fB\s-1XN_FLAG_SEP_COMMA_PLUS\s0\fR uses comma and plus as separators. \fB\s-1XN_FLAG_SEP_CPLUS_SPC\s0\fR
194uses comma and plus with spaces: this is more readable that plain comma and plus.
195\&\fB\s-1XN_FLAG_SEP_SPLUS_SPC\s0\fR uses spaced semicolon and plus. \fB\s-1XN_FLAG_SEP_MULTILINE\s0\fR uses
196spaced newline and plus respectively.
197.PP
198If \fB\s-1XN_FLAG_DN_REV\s0\fR is set the whole \s-1DN\s0 is printed in reversed order.
199.PP
200The 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,
201\&\fB\s-1XN_FLAG_FN_NONE\s0\fR determine how a field name is displayed. It will
202use the short name (e.g. \s-1CN\s0) the long name (e.g. commonName) always
203use \s-1OID\s0 numerical form (normally OIDs are only used if the field name is not
204recognised) and no field name respectively.
205.PP
206If \fB\s-1XN_FLAG_SPC_EQ\s0\fR is set then spaces will be placed around the '=' character
207separating field names and values.
208.PP
209If \fB\s-1XN_FLAG_DUMP_UNKNOWN_FIELDS\s0\fR is set then the encoding of unknown fields is
210printed instead of the values.
211.PP
212If \fB\s-1XN_FLAG_FN_ALIGN\s0\fR is set then field names are padded to 20 characters: this
213is only of use for multiline format.
214.PP
215Additionally all the options supported by \fIASN1_STRING_print_ex()\fR can be used to
216control how each field value is displayed.
217.PP
218In addition a number options can be set for commonly used formats.
219.PP
220\&\fB\s-1XN_FLAG_RFC2253\s0\fR sets options which produce an output compatible with \s-1RFC2253\s0 it
221is equivalent to:
222 \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
223.PP
224\&\fB\s-1XN_FLAG_ONELINE\s0\fR is a more readable one line format which is the same as:
225 \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
226.PP
227\&\fB\s-1XN_FLAG_MULTILINE\s0\fR is a multiline format which is the same as:
228 \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
229.PP
230\&\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.
