I use this in HyperHelp to find out how much memory to Alloc.
I this value with debug_flags_on, and it does agree with
what "list" reports.

Here is working and tested (though not complete) example code:

#include <libraries/dos.h>
#include <libraries/dosextens.h>

	struct FileInfoBlock *fileinfo=0;
	struct  Lock *lock=0,*Lock();        /* to get info about the disk */
	long len;

	if( (fileinfo=(struct FileInfoBlock *)AllocMem(sizeof(struct FileInfoBlock),0))==0) {
		goto fail;
	}
	if( (lock=Lock(name,ACCESS_READ))==0) {
		goto fail;
	}
	if(0==Examine(lock,fileinfo)){
		goto fail;
	}
	if(fileinfo->fib_DirEntryType>=0){ /* Is it a regular file? */
		goto fail; /* Nope, must be a directory */
	}

	len = fileinfo->fib_Size;

	if (fileinfo) FreeMem(fileinfo,sizeof(struct FileInfoBlock));
	fileinfo=0;
UnLock(lock);
