MLGetInteger64List() allocates memory for the array of integers. You must call (NonWLLink[MLReleaseInteger64List(), paclet:ref/c/MLReleaseInteger64List]) to disown this memory. If MLGetInteger64List() fails and the function's return value indicates an error, do not call (NonWLLink[MLReleaseInteger64List(), paclet:ref/c/MLReleaseInteger64List]) on the contents of a.

MLGetInteger64List() returns immutable data.

MLGetInteger64List() returns 0 in the event of an error, and a nonzero value if the function succeeds.

Use (NonWLLink[MLError(), paclet:ref/c/MLError]) to retrieve the error code if MLGetInteger64List() fails.

MLGetInteger64List() is declared in the MathLink header file (RefLink[mathlink.h, paclet:ref/file/mathlink.h]).
