LDAP_COMPARE(3) OpenLDAP 2.2.23 (2005/01/24) LDAP_COMPARE(3)
NAME
ldap_compare, ldap_compare_s - Perform an LDAP compare
operation
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include <ldap.h>
int ldap_compare_s(ld, dn, attr, value)
LDAP *ld;
char *dn, *attr, *value;
int ldap_compare(ld, dn, attr, value)
LDAP *ld;
char *dn, *attr, *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 to compare to those found in
the entry. 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
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(3).
ERRORS
ldap_compare_s() returns an LDAP error code which can be
interpreted by calling one of ldap_perror(3) and friends.
ldap_compare() returns -1 if something went wrong initiating
the request. It returns the non-negative message id of the
request if things went ok.
BUGS
There is no way to compare binary values, but there should
be.
