ldap_compare, ldap_compare_s -- LDAP compare operations

Synopsis

#include <lber.h> 
#include <ldap.h> 

int ldap_compare_s(LDAP *ld, char *dn, char *attr, char *value);

int ldap_compare(LDAP *ld, char *dn, char *attr, char *value);

Description

The ldap_compare_s routine is used to perform an LDAP compare operation synchronously. It takes dn, the DN of the entry upon which to perform the compare, and attr and value, the attribute type and value with which those found in the entry will be compared. It returns an LDAP error code, which will be LDAP_COMPARE_TRUE if the entry contains the attribute value, and LDAP_COMPARE_FALSE if it does not. Otherwise, some other error code is returned.

The ldap_compare routine is used to perform an LDAP compare operation asynchronously. It takes the same parameters as ldap_compare_s, but returns the message ID of the request it initiated. The result of the compare can be obtained by a subsequent call to ldap_result(3ldap).

Note that there is no way to compare binary values.

Return values

ldap_compare_s returns an LDAP error code which can be interpreted by calling one of the routines documented on the ldap_perror(3ldap) manual page. ldap_compare returns -1 if initiating the request fails. It returns the non-negative message ID of the request on success.
