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?

To be more precise I had a global array with three pointers in it to char* buffers. i.e char* buf1, char* buf2 and so on.

I set the global array at a size of 50. So I had a 50 structures contain my three char pointers.

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 :-}. Cheers, Justin -- Justin C.
