Hi,

I need to create strings dynamically and thought of encapsulating it in a structure and accessing that thru a linked list like this:

struct MyStruct {
string strMyString;
} MyStructure, *ptFirstMyStruct, *ptThisMyStruct;

Then I thought of using malloc and free to allocate memory dynamically as follows:

ptFirstMyStruct = (struct MyStruct *) malloc (sizeof
( struct MyStruct));

. . .

free ((void *) ptFirstMyStruct);

But OriginC compilator sent me an exception of "Integer divided by zero", when I was building. That crashed and finished the whole Origin application.

Is there any special attention to be paid to compilation time when using malloc/free functions? In fact I am a beginner at using these functions and probably my doubts concern of basic concepts on that...

[By the way, does OriginC support C++ routines?]

Best Wishes,

Ricardo Carneiro

Not sure what you are looking for. Origin C in Origin 7 does not support C++ but next version of Origin (Origin 8) will have substantial support of C++. There is also going to be an XML based Tree built-in to the language then, so that making a linked list would
be a very simple matter.

Great News about next version of Origin, Mr. Yang!
That will enhance the tool substantially.

In the meantime I guess I will live with some static allocation
because the events in case are kind of predictable.
I was just trying to improve my code. Best Regards!
