This volume of POSIX.1\(hy2017 defers to the ISO\ C standard. +.P +The +.IR <stddef.h> +header shall define the following macros: +.IP NULL 10 +Null pointer constant. +The macro shall expand to an integer constant expression with the +value 0 cast to type +.BR "void *" . +.IP "offsetof(\fItype\fP, \fImember-designator\fP)" 10 +.br +Integer constant expression of type +.BR size_t , +the value of which is the offset in bytes to the structure member +(\fImember-designator\fP), from the beginning of its structure +(\fItype\fP). +.P +The +.IR <stddef.h> +header shall define the following types: +.IP "\fBptrdiff_t\fP" 10 +Signed integer type of the result of subtracting two pointers. +.IP "\fBwchar_t\fP" 10 +Integer type whose range of values can represent distinct codes for +all members of the largest extended character set specified among the +supported locales; the null character shall have the code value zero. Each +member of the basic character set shall have a code value equal to its +value when used as the lone character in an integer character constant +if an implementation does not define _\|_STDC_MB_MIGHT_NEQ_WC_\|_. +.IP "\fBsize_t\fP" 10 +Unsigned integer type of the result of the +.IR sizeof +operator. +.P +The implementation shall support one or more programming environments +in which the widths of +.BR ptrdiff_t , +.BR size_t , +and +.BR wchar_t +are no greater than the width of type +.BR long . +The names of these programming environments can be obtained using the +\fIconfstr\fR() +function or the +.IR getconf +utility. +.LP +.IR "The following sections are informative." +.SH "APPLICATION USAGE" +None. +.SH RATIONALE +The ISO\ C standard does not require the NULL macro to include the cast to type +.BR "void *" +and specifies that the NULL macro be implementation-defined.
