Until you use another Open, Dup, or Create system call for that path, you can no longer perform I/O to the file or device. </li> <li>If you close a path to a single-user device, the device becomes available to other requesting processes. NitrOS-9 deallocates internally managed buffers and descriptors. </li> <li>The Exit system call automatically closes all open paths. Therefore, you might not need to use the Close Path system call to close some paths. </li> <li>Do not close a standard I/O path unless you want to change the file or device to which it corresponds. </li> <li>Close Path performs an implied I$Detach call. If it causes the device link count to become 0, the device termination routine is executed. See I$Detach for additional information. </li> </ul></div>LothanFri, 27 Jun 2014 23:18:32 -0000https://sourceforge.netb9c310b1fdc8a8ae82aa276c3cbc2c9f530b22eb
