Allocate and Free memory

[_Jose_A__Guerrero_]

Hello forum:

I have used allocate and free C functions to obtain and delete data. It works ok, but when i move my plugin (filter) to another PC it crash. Is it this the right way to use memory in photoshop plugins? If not, could you give me an example of allocating and deallocating a double array for instance??

Thanks in advance

What development environment are you using?

On Windows, building plugins with VS6 and VS2005, I recently found that crashes could be caused by using malloc() to allocate data that is supposed to persist between plugin calls (such as the pb->parameters block). Changing to the pb->handleProcs calls fixed this issue. Using malloc()/free() within a single plugin entry does not appear to be a problem.

Im using VS6,
By the way, would you mind to give an example of use using handleProcs calls? As you can see, im starting with plugin programming
Thanks in advance

The SDK documents how you should and should not allocate memory.
You really need to use the Photoshop provided allocation routines to avoid running out of address space (and let Photoshop free some memory or address space as needed).
