SCODE ScCountProps(
int cprop,
LPSPropValue rgprop,
ULONG FAR * pcb
);
Parameters
cprop
[in] Count of properties in the array indicated by the rgprop parameter.rgprop
[in] Pointer to a range in an array of SPropValue 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 Value
S_OK
The call succeeded and has returned the expected value or values.MAPI_E_INVALID_PARAMETER
At least one 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 cause 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.
