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. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBERR_get_error\fR\|(3), \fBd2i_X509_NAME\fR\|(3), \&\fBOBJ_nid2obj\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2002\-2018 The OpenSSL Project Authors.
