Thread: Standard alternative to sizeof(array)/sizeof(array[0])?

Is there a good standard alternative to the

Code:

sizeof(array)/sizeof(array[0])

used for determining the size of an array?

Well sometimes you see:

Code:

sizeof array/sizeof*array

but this is only somewhat shorter and not hardly better.

What I'm looking for is a standard macro in a standard header, something like

Code:

#define lenof(a) (sizeof(a)/sizeof((a)[0]))

but there is no such thing in stddef.h where offsetof is defined.
There is the further problem, that

Code:

int foo(short array[8]) 
{
   return lenof(array);
}

will return 2 not 8 on most targets, due to the fact that foo is equal to

Code:

int foo(short *array)

which is a rather obscure feature of C.
