dio_open ( string filename, int flags [, int mode])
dio_open() opens a file and returns a new file
descriptor for it, or FALSE if any error occurred. If
flags is O_CREAT, the optional third parameter
mode will set the mode of the file
(creation permissions). The flags
parameter can be one of the following options:
O_RDONLY - opens the file for read access.
O_WRONLY - opens the file for write access.
O_RDWR - opens the file for both reading and
writing.
The
flags parameter can also include any
combination of the following flags:
O_CREAT - creates the file, if it doesn't already exist.
O_EXCL - if both, O_CREAT and O_EXCL are set,
dio_open() fails, if the file already exists.
O_TRUNC - if the file exists, and its opened for write access,
the file will be truncated to zero length.
O_APPEND - write operations write data at the
end of the file.
O_NONBLOCK - sets non blocking mode.
