.SH NAME
ldap_perror, ld_errno, ldap_result2error, ldap_errlist, ldap_err2string \- LDAP protocol error handling routines
.SH LIBRARY
OpenLDAP LDAP (libldap, \-lldap)
.SH SYNOPSIS
.nf
.ft B
#include <ldap.h>
.LP
.ft B
char *ldap_err2string( int \fIerr\fB );
.SH DESCRIPTION
The
.B 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; positive, 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
.BR ldap_get_option (3)
and
.BR ldap_set_option (3)
with the
.B LDAP_OPT_RESULT_CODE
option (previously called
.BR LDAP_OPT_ERROR_NUMBER ).

.SH 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 \fIregistered\fP LDAP result codes
can be obtained from the \fIInternet Assigned Numbers Authority\fP
<http://www.iana.org>.
