Re: Prototyping printf()

[Jim Langston <jimlangston@xxxxxxxxxxxxxxxx>]

I can think of absolutely no valid reason to store a pointer to a file.
When data is in a file it is assumed it is for storage.  The next time
you read the file there is no guarantee that the same data is going to
be in the location pointed to by the pointer!

Pointers point to some spot in memory, although it doesn't necessarily
have to be ROM since the AS/400 used dynamic memory.  Tomorrow I can
almost guarantee you that almost nothing will be in the same memory 
location (the exception being the kernel source which probably will be).
So writing a pointer to file for later use is worthless and downright
dangerous.
