OpenersNotesSection(Spacer1)Details

MLGetReal32List() allocates memory for the array of numbers. You must call (NonWLLink[MLReleaseReal32List(), paclet:ref/c/MLReleaseReal32List]) to disown this memory. If MLGetReal32List() fails and the function's return value indicates an error, do not call (NonWLLink[MLReleaseReal32List(), paclet:ref/c/MLReleaseReal32List]) on the contents of a.

External programs should not modify the array generated by MLGetReal32List().

MLGetReal32List() returns immutable data.

MLGetReal32List() 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 MLGetReal32List() fails.

MLGetReal32List() is declared in the MathLink header file (RefLink[mathlink.h, paclet:ref/file/mathlink.h]).
