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 );

       void ldap_perror( LDAP *ld, const char *s )

       int ldap_result2error( LDAP *ld, LDAPMessage *res, int freeit )

DESCRIPTION

       These routines  provide  interpretation  of  the  various  error  codes
       returned  by  the LDAP protocol and LDAP library routines or associated
       with an LDAP session.  The error 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).

       The  ldap_result2error()  routine  takes  res,  a result as produced by
       ldap_result(3) or ldap_search_s(3), and returns the corresponding error
       code.   Possible error codes are listed below.  If the freeit parameter
       is non zero it indicates that the res parameter should be  freed  by  a
       call  to  ldap_msgfree(3) after the error code has been extracted.  The
       ld_errno field in ld is set and returned.

       The returned value can be passed to ldap_err2string()  to  get  a  text
       description of the message.  The string returned from ldap_err2string()
       is a pointer to a static area that should not be modified.

       The ldap_perror() routine can be called to print an indication  of  the
       error on standard error, similar to the way perror(3) works.

ERRORS

       The possible values for an ldap error code are:

       LDAP_SUCCESS        The request was successful.
