OpenersNotesSection(Spacer1)Details

The array a is laid out in memory like a C array declared as mlint64 a[m][n]….

heads gives a list of character strings corresponding to the names of symbols that appear as heads at each level in the array.

MLGetInteger64Array() allocates memory which must be disowned by calling (NonWLLink[MLReleaseInteger64Array(), paclet:ref/c/MLReleaseInteger64Array]). If MLGetInteger64Array() fails and the function's return value indicates an error, do not call (NonWLLink[MLReleaseInteger64Array(), paclet:ref/c/MLReleaseInteger64Array]) on the contents of a.

MLGetInteger64Array() returns immutable data.

MLGetInteger64Array() 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 MLGetInteger64Array() fails.

MLGetInteger64Array() is declared in the MathLink header file (RefLink[mathlink.h, paclet:ref/file/mathlink.h]).
