instances (Sdk)
instances // Sdk
Feb 5, 2001, 2:07am
with the new 3.1 SDK my instances don't seem to be working... the
aw_create() uses a void** for an instance, but to set the instance it uses a
void*... Is my brain not working or is this an SDK problem?

The aw_create() uses a void ** in order to be able to return an void *.
See these examples and comments:
void *instance; // pointer to "void", to unknown data
void **p_instance; // pointer to a pointer to void.
aw_create(....,&instance); // takes the address of the pointer-to-void
which generates a pointer-to-pointer-to-void
p_instance = &instance; // same here
aw_create(...,p_instance); // this would work too
Hope that helps :)

void *instance[64]; // is a good example of the array of the pointers.

char *errortexts[]={"No error","One Error","Two Errors","Three
Errors",NULL}; // is a common example for pointer arrays
