LDAP_ERROR(3)              Library Functions Manual              LDAP_ERROR(3)

NAME
       ldap_perror, ld_errno, ldap_result2error, ldap_errlist, ldap_err2string
       - LDAP protocol error handling routines

LIBRARY
       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS
       #include <ldap.h>

       char *ldap_err2string( int err );

DESCRIPTION
       The ldap_err2string() routine provides short description of the various
       codes  returned  by routines in this library.  The returned string is a
       pointer to a static area that should not be modified.

       These codes are either negative, indicating an API  error  code;  posi-
       tive,  indicating  an  LDAP  resultCode  other than 'success' (0), or -
       zero, indicating both successful use of the API and the LDAP resultCode
       'success' (0).

       The   code   associated  with  an  LDAP  session  is  accessible  using
       ldap_get_option(3) and ldap_set_option(3) with the LDAP_OPT_RESULT_CODE
       option (previously called LDAP_OPT_ERROR_NUMBER).

PROTOCOL RESULT CODES
       This  section  provides  a partial list of protocol codes recognized by
       the library.  As LDAP is extensible, additional values may be returned.
       A complete listing of registered LDAP result codes can be obtained from
       the Internet Assigned Numbers Authority <http://www.iana.org>.

                           send to the LDAP server.

       LDAP_NO_MEMORY      An memory allocation (e.g., malloc(3) or other  dy-
                           namic  memory allocator) call failed in an ldap li-
                           brary routine.

       LDAP_USER_CANCELED  Indicates the user cancelled the operation.

       LDAP_CONNECT_ERROR  Indicates a connection problem.

       LDAP_NOT_SUPPORTED  Indicates the routine was called in  a  manner  not
                           supported by the library.

       LDAP_CONTROL_NOT_FOUND
                           Indicates  the  control  provided is unknown to the
                           client library.

                           processing.

       LDAP_REFERRAL_LIMIT_EXCEEDED
                           Indicates the referral limit has been exceeded.

DEPRECATED
       Deprecated  interfaces  generally  remain  in  the  library.  The macro
       LDAP_DEPRECATED can be defined to a non-zero value (e.g., -DLDAP_DEPRE-
       CATED=1)  when compiling program designed to use deprecated interfaces.
       It is recommended that developers writing new programs, or updating old
       programs,  avoid  use  of  deprecated interfaces.  Over time, it is ex-
       pected that documentation (and, eventually, support) for deprecated in-
       terfaces to be eliminated.
