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