ScCountProps 

The ScCountProps function determines the size, in bytes, of a property value array and validates the memory associated with the array.

Note  This function may not be supported in future versions of MAPI.

Quick Info

SCODE ScCountProps(

Parameters

cprop

[in] Count of properties in the array indicated by the rgprop parameter.

rgprop

[in] Pointer to a range in an array of SPropValue81C9._8 structures that defines the properties whose size is to be determined. This range does not necessarily start at the beginning of the array.

pcb

[out] Optional pointer to the size, in bytes, of the property array.

Return Values

S_OK

The call succeeded and has returned the expected value or values.

MAPI_E_INVALID_PARAMETER

A property in the property value array has an identifier of PROP_ID_NULL or PROP_ID_INVALID or the property array contains a multivalued property with no property values.

Remarks

If NULL is passed in the pcb parameter, the ScCountProps function validates the array of notifications but no counting is done. If a non-null value is passed in pcb, the ScCountNotifications function determines the size of the array and stores the result in pcb. The pcb parameter must be large enough to contain the entire array.

As it is counting, ScCountProps validates the memory associated with the array. ScCountProps only works with properties about which MAPI has information.
