Linux - Error : storage size of var not known

I am trying to use the stat() function under Linux, and am getting the
error:

storage size of 'stbuf' is not known

What is causing this? Code fragment is below. E-mail answer is preferable.

Thank you in advance.

-------- BEGIN INCLUDED CODE FRAGMENT --------

void fred(void)
{
    char *name;
    struct stat stbuf;
/*  also tried "struct new_stat stbuf;" */
/*  it seems Linux has struct old_stat (functionally the same as struct stat)
    and new_stat (old_stat with some other fields) */

    if(stat(name, &stbuf) != NULL)
    {
        /* do something */
    }
}

-------- END INCLUDED CODE FRAGMENT --------

Shouldn't you include sys/types.h & sys/stat.h?

Isn't the return of stat 0 on success and -1 on failure? (the opposite
sense that you use it)

If 'struct stat' is not declared, the size of "stbuf" is not known.
You included "stat.h"
	#include <stat.h>
or
	#include <sys/stat.h>
?  In anie case, look up the usage of "stat" in your book or "man"-page.
