pointers

I have a c pointer to a structre type called uchar4 which looks like

{
    uchar x; 
    uchar y; 
    uchar z; 
    uchar w;
}

I also have data passed in as uint8*. I'd like to create a uchar* pointing to the data at the uint8* so I've tried doing this:

uint8 *data_in;
uchar4 *temp = (uchar4*)data_in;

However, the first 8 bytes always seem to be wrong. Is there another way of doing this?

i have two pointers, char *str1; int *str2; if i look at the size of both the pointers lets assume str1=4 bytes str2=4 bytes str1++ will increment by 1 byte but if str2++ will increment 4 byte could anybody tell e the concept behind this? >>> More

In a C++ program that doesn't contain legacy C code, is there a guideline regarding the maximum number of levels of indirection that should be used in the source code?
