What does the comma operator , do?
...the output pointer, the value and and the value's type. This being C, not C++ with templates, we couldn't have a function take an arbitrary type, so we settled on a macro:
#define ASSIGN_INCR(p, val, type) ((*((type) *)(p) = (val)), (p) += sizeof(type))
By using the comma operator we were able ...

Which is faster : if (bool) or if(int)?
