hi ,

If I want to pass the array like temp[gid] (temp is an array of strcture cnt), the error message will say that "change the address space of pointer".

But I need to get the temp[gid]'s final value by passing the temp[gid] to other function.

Simple code as below

typedef struct {

int count;

} cnt;

void funcA(__global cnt * cnt_temp)

{

}

__kernel void photon(__global cnt * temp)

{

int gid = get_global_id(0);

funcA(temp[gid]);

}

regards.,
