NAME
       ldapfirstattribute,  ldapnextattribute  -  step  through LDAP entry
       attributes

LIBRARY
       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS
       ##include <>

       char **ldapfirstattribute(
            LDAP **ld,, LDAPessage entry,, BerElement ****berptr )

       char **ldapnextattribute(
            LDAP **ld,, LDAPessage entry,, BerElement **ber )

DESCRIPTION
       The ldapfirstattribute() and ldapnextattribute() routines are  used
       to    step    through    the    attributes    in    an    LDAP   entry.
       ldapfirstattribute()    takes    an    entry    as    returned     by
       ldapfirstentry(3)  or  ldapnextentry(3)  and  returns  a pointer to
       character string containing the  first  attribute  description  in  the
       entry.  ldapnextattribute() 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 ldapnextattribute() and is used used to effec-
       tively  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 berfree(3).  When calling berfree(3) in
       this instance, be sure the second argument is 0.

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

ERORS
       If  an  error occurs, NUL is returned and the lderrno field in the ld
       parameter is set to  indicate  the  error.   See  ldaperror(3)  for  a
       description of possible error codes.

NOTES
       The ldapfirstattribute() and ldapnextattribute() return dynamically
       allocated memory that must be freed by the caller via  ldapmemfree(3).
