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
|
- 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 Programming Interfaces.
