error info:

.tools.c(17775): error C2069: Cast from “void” to non-void
.tools.c(17775): error C2036: “void *” : unknown size

my code:

This function attempts to free the memory of one-dimensional array or two-dimensional array, but do not work.

cdef void free_memory(void* arr, int ndim, int rows):
    cdef int i
    if ndim == 1:
        free(<double*>arr)
    elif ndim == 2:
        for i in range(rows):
            free(<double*>arr[i])
        free(<double**>arr)
    else:
        raise ValueError("Unsupported number of dimensions (ndim must be 1 or 2).")

example:

cdef double** array = <double**> malloc(n * sizeof(double*)) 
free_memory(array , 2, n)

I have tried to modify it many times, including using gpt assistance, but it still doesn’t work.
