NAME
       io_readfile - open a file for reading

SYNTAX
       #include <io.h>

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

DESCRIPTION
       io_readfile sets d to the number of a new descriptor reading from the
       disk file named s, and returns 1.

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