+
+=head1 SYNOPSIS
+
+int X509_NAME_get_index_by_NID(X509_NAME *name,int nid,int lastpos);
+int X509_NAME_get_index_by_OBJ(X509_NAME *name,ASN1_OBJECT *obj, int lastpos);
+
+int X509_NAME_entry_count(X509_NAME *name);
+X509_NAME_ENTRY *X509_NAME_get_entry(X509_NAME *name, int loc);
+
+int X509_NAME_get_text_by_NID(X509_NAME *name, int nid, char *buf,int len);
+int X509_NAME_get_text_by_OBJ(X509_NAME *name, ASN1_OBJECT *obj, char *buf,int len);
+
+=head1 DESCRIPTION
+
+These functions allow an B<X509_NAME> structure to be examined. The
+B<X509_NAME> structure is the same as the B<Name> type defined in
+RFC2459 (and elsewhere) and used for example in certificate subject
+and issuer names.
+
+X509_NAME_get_index_by_NID() and X509_NAME_get_index_by_OBJ() retrieve
+the next index matching B<nid> or B<obj> after B<lastpos>. B<lastpos>
+should initially be set to -1. If there are no more entries -1 is returned.
+
+X509_NAME_entry_count() returns the total number of entries in B<name>.
+
+X509_NAME_get_entry() retrieves the B<X509_NAME_ENTRY> from B<name>
+corresponding to index B<loc>. Acceptable values for B<loc> run from
+0 to (X509_NAME_entry_count(name) - 1). The value returned is an
+internal pointer which must not be freed.
+
+X509_NAME_get_text_by_NID(), X509_NAME_get_text_by_OBJ() retrieve
+the "text" from the first entry in B<name> which matches B<nid> or
+B<obj>, if no such entry exists -1 is returned. At most B<len> bytes
+will be written and the text written to B<buf> will be null
+terminated. The length of the output string written is returned
+excluding the terminating null. If B<buf> is <NULL> then the amount
+of space needed in B<buf> (excluding the final null) is returned. 
+
+=head1 NOTES
+
+X509_NAME_get_text_by_NID() and X509_NAME_get_text_by_OBJ() are
+legacy functions which have various limitations which make them
+of minimal use in practice. They can only find the first matching
+entry and will copy the contents of the field verbatim: this can
+be highly confusing if the target is a muticharacter string type
+like a BMPString or a UTF8String.
+
+For a more general solution X509_NAME_get_index_by_NID() or
+X509_NAME_get_index_by_OBJ() should be used followed by
+X509_NAME_get_entry() on any matching indices and then the
+various B<X509_NAME_ENTRY> utility functions on the result.
+
+=head1 EXAMPLES
+
+Process all entries:
+
+ int i;
+ X509_NAME_ENTRY *e;
+
+ for (i = 0; i < X509_NAME_entry_count(nm); i++)
+	{
+	e = X509_NAME_get_entry(nm, i);
+	/* Do something with e */
+	}
+
+Process all commonName entries:
+
+ int loc;
+ X509_NAME_ENTRY *e;
+
+ loc = -1;
+ for (;;)
+	{
+	lastpos = X509_NAME_get_index_by_NID(nm, NID_commonName, lastpos);
+	if (lastpos == -1)
+		break;
+	e = X509_NAME_get_entry(nm, lastpos);
+	/* Do something with e */
+	}
+
+=head1 RETURN VALUES
+
+X509_NAME_get_index_by_NID() and X509_NAME_get_index_by_OBJ()
+return the index of the next matching entry or -1 if not found.
+
+X509_NAME_entry_count() returns the total number of entries.
+
+X509_NAME_get_entry() returns an B<X509_NAME> pointer to the
+requested entry or B<NULL> if the index is invalid.
