Passing R/W arrays to external libraries

[Rado1]

Is it possible to pass an array as parameter to external library and change values of array by the library? All my trials ended up with access violation errors.

ZExternalLibrary:

Code: Select all

void foo(int[] arr) {}

Call from ZExpression:

Code: Select all

int[10] arr;
foo(arr);

Here is the corresponding C++ code:

Code: Select all

export void foo(int* arr) {
	int i = 0;
	for(int i = 0; i < 10; ++i)
		arr[i] = i;
}

Hi Rado1,

Sure, simply use xptr as argument type

Thanks Kjell! Stupid me. At the moment I'm using C++, Java, expression language for a technology we are developing in company, ZGE expressions... so sometimes I cannot remember proper constructs. Thanks again.

Rado1.
