It is a bitwise OR of zero or more of the following flags: .PP .TP .B O_CREAT Indicates that an XRCD should be created and associated with the inode referenced by the given fd. If the XRCD exists, this flag has no effect except as noted under .BR O_EXCL below.\fR .TP .B O_EXCL If .BR O_EXCL and .BR O_CREAT are set, open will fail if an XRCD associated with the inode exists. .PP If .I fd equals -1, no inode is associated with the XRCD.
