ldap_first_attribute,  ldap_next_attribute  - step through
       LDAP entry attributes


SYNOPSIS

       #include <ldap.h>

       char *ldap_first_attribute(ld, entry, berptr)
       LDAP *ld;
       LDAPMessage *entry;
       BerElement **berptr;

       char *ldap_next_attribute(ld, entry, ber)
       LDAP *ld;
       LDAPMessage *entry;
       BerElement *ber;


DESCRIPTION

       The ldap_first_attribute() and ldap_next_attribute()  rou­
       tines  are  used to step through the attributes in an LDAP
       entry.  ldap_first_attribute() takes an entry as  returned
       by ldap_first_entry(3) or ldap_next_entry(3) and returns a
       pointer to character string containing the first attribute
       description  in  the entry.  ldap_next_attribute() returns
       the next attribute description in the entry.

       It also returns, in berptr, a pointer to a  BerElement  it
       has allocated to keep track of its current position.  This
       pointer  should  be  passed   to   subsequent   calls   to
       ldap_next_attribute() and is used used to effectively step
       through the entry's  attributes.   The  caller  is  solely
       responsible  for  freeing  the  BerElement  pointed  to by
       berptr when it is no longer needed by calling ber_free(3).
       When  calling  ber_free(3)  in  this instance, be sure the
       second argument is 0.

       The attribute names returned are suitable for inclusion in
       a  call  to ldap_get_values(3) to retrieve the attribute's
       values.


ERRORS

       If an error occurs, NULL  is  returned  and  the  ld_errno
       field  in  the  ld parameter is set to indicate the error.
       See ldap_error(3) for  a  description  of  possible  error
       codes.


NOTES

       The  ldap_first_attribute() routine dyanamically allocated
       memory that must be freed  by  the  caller  via  ldap_mem­
       free(3).
