dynamically allocate a 2D array

[tom3]

Hello
I have an 2D array

Code: Select all

my_array[i][j]

. "i" is a fixed number but i want "j" to be chosen by the user ( like an input). Then i want to create the 2D array using the input given by the user. I have tried several methods to do that, but the problem is that it won't let me do that. For example , i can't define

Code: Select all

int **my_array 

. The error says " cannot declare pointer to aliasing pointer".
Of course , i have checked the AN10001 to pass an alias pointer as argument, but since i want to use the code :

Code: Select all

my_array=(int **)malloc(input_user * sizeof(int *));

, it makes everything a little more difficult because of the "int **" since this isn't a variable but just a type.

Does somebody know a trick to do that ? I would be very grateful. I have seen many methods online, but they can't be applied to XMOS programming because of the restrictions it has .

Thank you in advance

Best regards
