OFFSETOF(3)		     Library Functions Manual		     OFFSETOF(3)

NAME
     offsetof -- offset of a structure member

SYNOPSIS
     #include <stddef.h>

     size_t
     offsetof(type, member);

DESCRIPTION
     The  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).

STANDARDS
     The offsetof() macro conforms to ANSI X3.159-1989 ("ANSI C89").

FreeBSD ports 15.quarterly	February 18, 2010		     OFFSETOF(3)
