LDAP_COMPARE(3)        C LIBRARY FUNCTIONS        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 com-
     pare  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 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.
