PHP supports the direct io functions as described in the Posix
Standard (Section 6) for performing I/O functions at a lower
level than the C-Language stream I/O functions (fopen, fread,..).
Estas fun��es s�o disponibilizadas como parte de um
m�dulo padr�o, e est�o sempre dispon�veis.
To get these functions to work, you have to configure PHP with
--enable-dio.

a file descriptor returnded by dio_open().
Esta extens�o n�o define nenhuma constante.
