LDAP_COMPARE(3)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 com-
pare operation asynchronously. It takes the same parame-
ters 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).
ERRORSldap_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 initiat-
ing 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.
