Returns the unsigned 32-bit value at the specified memory
location as an INT64. This is analogous to the GET-UNSIGNED-SHORT
function, except with a 32-bit value.
Syntax
GET-UNSIGNED-LONG ( source , position )
|
-
source
- A function or variable that returns a RAW or MEMPTR value. If source is
the Unknown value (?), GET-UNSIGNED-LONG returns the Unknown value (?).
-
position
- An INTEGER or INT64 value greater than 0 that indicates the
byte position where you want to find the information. If position is
greater than the length of source, the AVM returns
the Unknown value (?). If position is
less than 1, the AVM generates a run-time error.
Notes
- When
returning the value from GET-UNSIGNED-LONG() to an INTEGER, if the
value exceeds the maximum value of an INTEGER, the AVM generates
a run-time error.
- This function supports byte-swapping only if source is
a MEMPTR data type. The function will first examine the byte-order
setting of the MEMPTR and then swap the bytes appropriately before
interpreting them. The AVM does not swap the bytes in the MEMPTR's
memory, but does the byte-swap as it creates the return value.
- For more information on using the MEMPTR and RAW data types, see OpenEdge
