NAME¶

UlPropSize (MAPI32.77)

SYNOPSIS¶

ULONG UlPropSize
(
LPSPropValue lpProp
)

DESCRIPTION¶

Determine the size of a property in bytes.

PARAMS¶

lpProp [In] Property to determine the size of.

RETURNS¶

Success: The size of the value in lpProp. Failure: 0, if a multi-value (array) property is invalid or the type of lpProp is unknown.

NOTES¶

- The size returned does not include the size of the SPropValue struct or the size of the array of pointers for multi-valued properties that contain pointers (such as PT_MV_STRING8 or PT-MV_UNICODE). - MSDN incorrectly states that this function returns MAPI_E_CALL_FAILED if lpProp is invalid. In reality no checking is performed and this function will crash if passed an invalid property, or return 0 if the property type is PT_OBJECT or is unknown.

IMPLEMENTATION¶

Declared in "mapiutil.h". Implemented in "dlls/mapi32/prop.c". Debug channel "mapi".
