Under Linux, the O_NONBLOCK flag indicates that one wants to open but does not necessarily have the intention to read or write. This is typically used to open devices in order to get a file descriptor for use with ioctl (2) . Before Linux 2.6.33, Linux implemented only the O_SYNC flag for open(). However, when that flag was specified, most filesystems actually provided the equivalent of synchronized I/O data integrity completion (i.e., O_SYNC was actually implemented as the equivalent of O_DSYNC ). The open() function shall return a file descriptor for the named file that is the lowest file descriptor not currently open for that process. The open file description is new, and therefore the file descriptor shall not share it with any other process in the system. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
