MLGetReal64List()

int MLGetReal64List(MLINK link, double **a, int *n)
gets a list of double-precision floating-point numbers from the MathLink connection specified by link, storing the numbers in array a and the length of the list in n.

MORE INFORMATION

MLGetReal64List() allocates memory for the array of numbers. You must call MLReleaseReal64List() to disown this memory. If MLGetReal64List() fails and the function's return value indicates an error, do not call MLReleaseReal64List() on the contents of a.

MLGetReal64List() returns immutable data.

MLGetReal64List() returns 0 in the event of an error, and a nonzero value if the function succeeds.

Use MLError() to retrieve the error code if MLGetReal64List() fails.

MLGetReal64List() is declared in the MathLink header file mathlink.h.
