31=head1 DESCRIPTION
32
33X509_NAME_ENTRY_get_object() retrieves the field name of B<ne> in
34and B<ASN1_OBJECT> structure.
35
36X509_NAME_ENTRY_get_data() retrieves the field value of B<ne> in
37and B<ASN1_STRING> structure.
38
39X509_NAME_ENTRY_set_object() sets the field name of B<ne> to B<obj>.
40
41X509_NAME_ENTRY_set_data() sets the field value of B<ne> to string type
42B<type> and value determined by B<bytes> and B<len>.
43
44X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID()
45and X509_NAME_ENTRY_create_by_OBJ() create and return an
46B<X509_NAME_ENTRY> structure.
47
48=head1 NOTES
49
50X509_NAME_ENTRY_get_object() and X509_NAME_ENTRY_get_data() can be
51used to examine an B<X509_NAME_ENTRY> function as returned by
52X509_NAME_get_entry() for example.
53
54X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_OBJ(),
55X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_set_data()
56are seldom used in practice because B<X509_NAME_ENTRY> structures
57are almost always part of B<X509_NAME> structures and the
58corresponding B<X509_NAME> functions are typically used to
59create and add new entries in a single operation.
60
61The arguments of these functions support similar options to the similarly
62named ones of the corresponding B<X509_NAME> functions such as
63X509_NAME_add_entry_by_txt(). So for example B<type> can be set to
64B<MBSTRING_ASC> but in the case of X509_set_data() the field name must be
65set first so the relevant field information can be looked up internally.
66
67=head1 RETURN VALUES
68
69X509_NAME_ENTRY_get_object() returns a valid B<ASN1_OBJECT> structure if it is
70set or NULL if an error occurred.
71
72X509_NAME_ENTRY_get_data() returns a valid B<ASN1_STRING> structure if it is set
73or NULL if an error occurred.
74
75X509_NAME_ENTRY_set_object() and X509_NAME_ENTRY_set_data() return 1 on success
76or 0 on error.
77
78X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and
79X509_NAME_ENTRY_create_by_OBJ() return a valid B<X509_NAME_ENTRY> on success or
80NULL if an error occurred.
