int \fBio_appendfile\fP(int64* d,const char* s);
.SH DESCRIPTION
io_appendfile sets d to the number of a new descriptor writing to the
end of the disk file named \fIs\fR, and returns 1.  If the file does not
exist, it will be created with mode 0600.

If something goes wrong, io_appendfile sets \fIerrno\fR to indicate the error, and
returns 0; it does not create a new descriptor, and it does not touch d.
