I have tested the above code on my FC3 system. It is working fine. Coming to the size restrictions, the compiler allocates the sizes for the structures in the multiple of 4 always. If you have the structure like struct size_test { int a; char b; }abc; If you print the size of the above structure variable (abc) it shows you 8. Bye the bye, what version of kernel is you using?
