SYNOPSIS
       int X509_NAME_add_entry_by_txt(X509_NAME *name, char
       *field, int type, unsigned char *bytes, int len, int
       loc, int set); int X509_NAME_add_entry_by_OBJ(X509_NAME
       *name, ASN1_OBJECT *obj, int type, unsigned char *bytes,
       int len, int loc, int set); int
       X509_NAME_add_entry_by_NID(X509_NAME *name, int nid, int
       type, unsigned char *bytes, int len, int loc, int set);
       int X509_NAME_add_entry(X509_NAME *name,X509_NAME_ENTRY
       *ne, int loc, int set); X509_NAME_ENTRY
       *X509_NAME_delete_entry(X509_NAME *name, int loc);

DESCRIPTION
       X509_NAME_add_entry_by_txt(),
       X509_NAME_add_entry_by_OBJ() and
       X509_NAME_add_entry_by_NID() add a field whose name is
       defined by a string field, an object obj or a NID nid
       respectively.  The field value to be added is in bytes
       of length len. If len is -1 then the field length is
       calculated internally using strlen(bytes).

       The type of field is determined by type which can either
       be a definition of the type of bytes (such as
       MBSTRING_ASC) or a standard ASN1 type (such as
       V_ASN1_IA5STRING). The new entry is added to a position
       determined by loc and set.

       X509_NAME_add_entry() adds a copy of X509_NAME_ENTRY
       structure ne to name. The new entry is added to a posi-
       tion determined by loc and set. Since a copy of ne is
       added ne must be freed up after the call.

       X509_NAME_delete_entry() deletes an entry from name at
       position loc. The deleted entry is returned and must be
       freed up.

NOTES
       The use of string types such as MBSTRING_ASC or
       MBSTRING_UTF8 is strongly recommened for the type param-
       eter. This allows the internal code to correctly deter-
       mine the type of the field and to apply length checks
       according to the relevant standards. This is done using
       ASN1_STRING_set_by_NID().

       If instead an ASN1 type is used no checks are performed
       and the supplied data in bytes is used directly.

       In X509_NAME_add_entry_by_txt() the field string repre-
       sents the field name using OBJ_txt2obj(field, 0).

       The loc and set parameters determine where a new entry
       should be added. For almost all applications loc can be
       set to -1 and set to 0. This adds a new entry to the end
       of name as a single valued RelativeDistinguishedName
       (RDN).

       loc actually determines the index where the new entry is
       inserted: if it is -1 it is appended.

       set determines how the new type is added. If it is zero
       a new RDN is created.

       If set is -1 or 1 it is added to the previous or next
       RDN structure respectively. This will then be a multi-
       valued RDN: since multivalues RDNs are very seldom used
       set is almost always set to zero.

EXAMPLES
       Create an X509_NAME structure:

       "C=UK, O=Disorganized Organization, CN=Joe Bloggs"

        X509_NAME *nm;
        nm = X509_NAME_new();
        if (nm == NULL)
               /* Some error */
        if (!X509_NAME_add_entry_by_txt(nm, MBSTRING_ASC,
                               "C", "UK", -1, -1, 0))
               /* Error */
        if (!X509_NAME_add_entry_by_txt(nm, MBSTRING_ASC,
                               "O", "Disorganized Organization", -1, -1, 0))
               /* Error */
        if (!X509_NAME_add_entry_by_txt(nm, MBSTRING_ASC,
                               "CN", "Joe Bloggs", -1, -1, 0))
               /* Error */

RETURN VALUES
       X509_NAME_add_entry_by_txt(),
       X509_NAME_add_entry_by_OBJ(),
       X509_NAME_add_entry_by_NID() and X509_NAME_add_entry()
       return 1 for success of 0 if an error occurred.

       X509_NAME_delete_entry() returns either the deleted
       X509_NAME_ENTRY structure of NULL if an error occurred.

BUGS
       type can still be set to V_ASN1_APP_CHOOSE to use a dif-
       ferent algorithm to determine field types. Since this
       form does not understand multicharacter types, performs
       no length checks and can result in invalid field types
       its use is strongly discouraged.
