-=head1 NAME
-X509_NAME_get_index_by_NID, X509_NAME_get_index_by_OBJ, X509_NAME_get_entry,
-X509_NAME_entry_count, X509_NAME_get_text_by_NID, X509_NAME_get_text_by_OBJ -
-X509_NAME lookup and enumeration functions
-=head1 SYNOPSIS
- #include <openssl/x509.h>
- 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);
-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.
-If B<nid> is invalid (doesn't correspond to a valid OID) then -2 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.
-The list of all relevant B<NID_*> and B<OBJ_* codes> can be found in
-the source code header files E<lt>openssl/obj_mac.hE<gt> and/or
-Applications which could pass invalid NIDs to X509_NAME_get_index_by_NID()
-should check for the return value of -2. Alternatively the NID validity
-can be determined first by checking OBJ_nid2obj(nid) is not NULL.
-=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 lastpos = -1;
- X509_NAME_ENTRY *e;
- 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 */
- }
-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_get_index_by_NID() can also return -2 if the supplied
-NID is invalid.
-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.
