OK let me try it another way.
I have this structure declared as global:
Struct Frame_Data
{
void *buff1;
void *buff2;
void *buff3;
}
Then I declare as a global:
Int g_Array_Cnt = 0;
struct Frame_Data my_data[50];
So in my kernel's init routine I do:
While(g_Array_Cnt < 50)
{
if((my_data[g_Array_Cnt].buff1 = _MALLOC(1600, M_TEMP,
M_WAITOK)) != 0)
{
bzero(&my_data[g_Array_Cnt].buff1, 1600);
if((my_data[g_Array_Cnt].buff2 = _MALLOC(1600, M_TEMP,
M_WAITOK)) != 0)
{
bzero(&my_data[g_Array_Cnt].buff2, 1600);
if((my_data[g_Array_Cnt].buff3 = _MALLOC(1600,
M_TEMP, M_WAITOK)) != 0)
{
bzero(&my_data[g_Array_Cnt].buff3,
1600);
}
else
// error handling
}
else
// error handling
}
else
// error handling
g_Array_Cnt++;
}
As I was saying g_Array_Cnt will go up to 10, go through the first
_MALLOC for buff1, then in poof, g_Array_Cnt becomes 0 and the process
will keep looping, from 0 to 10.
Does that make it clearer?

And, right away, I take it off-list :-}

I'm having trouble reading the above. It's not quite english :-}.
Maybe you need to put a governor on your brain, so it doesn't outrun
your fingers :-}.
