NAMEoffsetof — offset of a structure member
SYNOPSIS#include < stddef.h>
offsetof( type, member);
DESCRIPTIONThe offsetof() macro expands to an integer constant expression of type size_t and yields the offset, in bytes, of the field member from the start of the structure type.
A compiler error will result if member is not aligned to a byte boundary (i.e. it is a bit-field).
STANDARDSThe offsetof() macro conforms to ANSI X3.159-1989 (“ANSI C89”).
