Question

I need to pass a 2D array into the method below:

int pipeChild_1(int pipedes[], char *argsArray[][]);

But the compiler gives that error:

array has incomplete element type 'char *[]'

Answer 1

Unfortunately you can’t do that – ‘c’ only knows about pointers not about arrays.

If the size of the array is fixed (or at least the last dimension) you can pass that to the function, but a more common method is to pass a pointer to the array and the dimensions separately

eg Passing multidimensional arrays as function arguments in C or http://c-faq.com/aryptr/pass2dary.html
