There is a very thin line between the way various encodings that can be given to combinations of arrays and pointers in IDL files. Consider the following examples:
[size_is(…)] int data[] - Inline array of integers [size_is(…)] int *data - Pointer to array of integers [size_is(…)] int *data[] - Array of pointers followed by array of integers [size_is(,…)] int *data[] - Pointer to an array of integers
Summarizing the meaning of the operators:
- [] stands for an in-line array
- * is a pointer, possibly to an array
