LDAPSortKeyA structure (winldap.h)
The LDAPSortKey structure stores sorting criteria for use by sort controls.
Syntax
typedef struct ldapsortkeyA {
PCHAR sk_attrtype;
PCHAR sk_matchruleoid;
BOOLEAN sk_reverseorder;
} LDAPSortKeyA, *PLDAPSortKeyA;
Members
sk_attrtype
Pointer to a null-terminated string that specifies the name of the attribute to use as a sort key. Use multiple LDAPSortKey structures to specify multiple sort keys. Be aware that Active Directory supports only a single sort key.
sk_matchruleoid
Pointer to a null-terminated string that specifies the object identifier of the matching rule for the sort. Should be set to NULL if you do not want to explicitly specify a matching rule for the sort. Specifying an explicitly set matching rule is supported only by Windows Server 2003.
sk_reverseorder
If TRUE, specifies that the sort be ordered from lowest to highest. If FALSE, the sort order is from highest to lowest.
Remarks
The ldap_create_sort_control and ldap_search_init_page functions use this structure to specify how results should be sorted before being returned to the client.
Note
The winldap.h header defines LDAPSortKey as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
