Trying to understand pointers, basically i created a M[x][y] array, a pointer to said array *p_M[x] and a pointer to said pointer **d_p_M; the first pointer point to the first element of a row in the array M, and the double pointer points to the first row in *p...

Double pointers are instrumental in dynamically allocating memory for 2D arrays. This is because a 2D array can be thought of as an array of pointers, where each pointer corresponds to a row in the array. Declaring, Allocating, and Freeing 2D Arrays To dynamically create a 2D array, you fir...
edit: Ignore the unknown in the request close line, I am logging that before retrieving the stream pointer since I wanted to make sure the log line was as early as possible. ContributorAuthor mdouglasscommentedJun 17, 2021 So I was trying to figure out how we ended up re-entrant. It lo...
If x is a double, then &x is a pointer to a double So if ptr is a pointer to a pointer to an int, then &ptr is a pointer to a pointer to a pointer to an int. If you're meant to pass a pointer to a pointer to an int, do not pass a pointer to a pointer to a pointer...
4.1 As webJose as mentioned, you can use the IntPtr as the parameter type for receiving a pointer to an unmanaged 2D array of double values. 4.2 You may pre-allocate the memory for the 2D array in global memory and return a pointer to this memory. ...

Now, since the number of parts in a drawing is unknown, I think I might need my first pointer (double *ptr) to point to a dynamic list, then my second pointer (double **ptr) to point to the relative position arrays (double a_pos[12], b_pos[12], c_pos[12],...etc) ...
