NAME
       io_appendfile - open a file for appending

SYNTAX
       #include <io.h>

       int io_appendfile(int64* d,const char* s);

DESCRIPTION
       io_appendfile  sets  d  to the number of a new descriptor writing to the end of the disk file named s, and returns 1.  If the file does not
       exist, it will be created with mode 0600.

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