       X509_NAME_ENTRY_get_object() retrieves the field name of ne in and
       ASN1_OBJECT structure.

       X509_NAME_ENTRY_get_data() retrieves the field value of ne in and
       ASN1_STRING structure.

       X509_NAME_ENTRY_set_object() sets the field name of ne to obj.

       X509_NAME_ENTRY_set_data() sets the field value of ne to string type
       type and value determined by bytes and len.

       X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and
       X509_NAME_ENTRY_create_by_OBJ() create and return an X509_NAME_ENTRY

       X509_NAME_ENTRY_get_object() and X509_NAME_ENTRY_get_data() can be used
       to examine an X509_NAME_ENTRY function as returned by
       X509_NAME_get_entry() for example.

       X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_OBJ(),
       X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_set_data() are
       seldom used in practice because X509_NAME_ENTRY structures are almost
       always part of X509_NAME structures and the corresponding X509_NAME
       functions are typically used to create and add new entries in a single

       The arguments of these functions support similar options to the
       similarly named ones of the corresponding X509_NAME functions such as
       X509_NAME_add_entry_by_txt(). So for example type can be set to
       MBSTRING_ASC but in the case of X509_set_data() the field name must be
       set first so the relevant field information can be looked up

       X509_NAME_ENTRY_get_object() returns a valid ASN1_OBJECT structure if
       it is set or NULL if an error occurred.

       X509_NAME_ENTRY_get_data() returns a valid ASN1_STRING structure if it
       is set or NULL if an error occurred.

       X509_NAME_ENTRY_set_object() and X509_NAME_ENTRY_set_data() return 1 on
       success or 0 on error.

       X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and
       X509_NAME_ENTRY_create_by_OBJ() return a valid X509_NAME_ENTRY on
       success or NULL if an error occurred.
