DESCRIPTION	creat_____
creates a new file or prepares to rewrite an existing
file called name____;
name____ is the address of a null-terminated string.
If the file did not exist, it is given mode mode____;
if it did exist, its mode and owner remain unchanged
but it is truncated to 0 length.
The file is also opened for writing, and its file descriptor
is returned in r0.
The mode____ given is arbitrary; it need not allow
This feature is used by programs which deal with temporary
files of fixed names.  The creation is done with
a mode that forbids writing.  Then if a second
instance of the program attempts a creat_____, an error is
returned and the program knows that the name is unusable
for the moment.
