\&\fBX509_NAME_ENTRY_get_object()\fR retrieves the field name of \fBne\fR in
and \fB\s-1ASN1_OBJECT\s0\fR structure.
.PP
\&\fBX509_NAME_ENTRY_get_data()\fR retrieves the field value of \fBne\fR in
and \fB\s-1ASN1_STRING\s0\fR structure.
.PP
\&\fBX509_NAME_ENTRY_set_object()\fR sets the field name of \fBne\fR to \fBobj\fR.
.PP
\&\fBX509_NAME_ENTRY_set_data()\fR sets the field value of \fBne\fR to string type
\&\fBtype\fR and value determined by \fBbytes\fR and \fBlen\fR.
.PP
\&\fBX509_NAME_ENTRY_create_by_txt()\fR, \fBX509_NAME_ENTRY_create_by_NID()\fR
and \fBX509_NAME_ENTRY_create_by_OBJ()\fR create and return an
\&\fBX509_NAME_ENTRY\fR structure.
.SH "NOTES"
.IX Header "NOTES"
\&\fBX509_NAME_ENTRY_get_object()\fR and \fBX509_NAME_ENTRY_get_data()\fR can be
used to examine an \fBX509_NAME_ENTRY\fR function as returned by
\&\fBX509_NAME_get_entry()\fR for example.
.PP
\&\fBX509_NAME_ENTRY_create_by_txt()\fR, \fBX509_NAME_ENTRY_create_by_OBJ()\fR,
\&\fBX509_NAME_ENTRY_create_by_NID()\fR and \fBX509_NAME_ENTRY_set_data()\fR
are seldom used in practice because \fBX509_NAME_ENTRY\fR structures
are almost always part of \fBX509_NAME\fR structures and the
corresponding \fBX509_NAME\fR functions are typically used to
create and add new entries in a single operation.
.PP
The arguments of these functions support similar options to the similarly
named ones of the corresponding \fBX509_NAME\fR functions such as
\&\fBX509_NAME_add_entry_by_txt()\fR. So for example \fBtype\fR can be set to
\&\fB\s-1MBSTRING_ASC\s0\fR but in the case of \fBX509_set_data()\fR the field name must be
set first so the relevant field information can be looked up internally.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBX509_NAME_ENTRY_get_object()\fR returns a valid \fB\s-1ASN1_OBJECT\s0\fR structure if it is
set or \s-1NULL\s0 if an error occurred.
.PP
\&\fBX509_NAME_ENTRY_get_data()\fR returns a valid \fB\s-1ASN1_STRING\s0\fR structure if it is set
or \s-1NULL\s0 if an error occurred.
.PP
\&\fBX509_NAME_ENTRY_set_object()\fR and \fBX509_NAME_ENTRY_set_data()\fR return 1 on success
or 0 on error.
.PP
\&\fBX509_NAME_ENTRY_create_by_txt()\fR, \fBX509_NAME_ENTRY_create_by_NID()\fR and
\&\fBX509_NAME_ENTRY_create_by_OBJ()\fR return a valid \fBX509_NAME_ENTRY\fR on success or
\&\s-1NULL\s0 if an error occurred.
