* cached by IO_CLOSE. To make sure a file descriptor is really closed call
* IH_REALLYCLOSE.
*
+ * Note that IH_REALLYCLOSE does not guarantee that all file descriptors are
+ * closed (or are marked as needing close) by the time it returns, in the case
+ * of an IH_OPEN being executed in parallel. If a separate thread is running
+ * an IH_OPEN on the same IHandle_t at around the same time, it is possible for
+ * it to open the file, then IH_REALLYCLOSE runs, and then IH_OPEN associates
+ * the file handle with the IHandle_t. For this reason, it is probably an
+ * error if it is ever possible to have an IH_OPEN call run at the same time as
+ * an IH_REALLYCLOSE call on the same IHandle_t. If such functionality is
+ * required, ihandle must be changed to accomodate this.
+ *
* The IHandle_t also provides a place to do other optimizations. In the
* NT user space file system, we keep a separate special file for the
* link counts and using the IHandle_t allows keeping the details of
*
* Replacements for C runtime file operations
* FDH_READ/FDH_WRITE - read/write using the file descriptor.
- * FDH_READV/FDH_WRITEV - readv/writev (Unix only)
* FDH_SEEK - set file handle's read/write position
* FDH_CLOSE - return a file descriptor to the cache
* FDH_REALLYCLOSE - Close a file descriptor, do not return to the cache
* status information:
* FDH_SIZE - returns the size of the file.
* FDH_NLINK - returns the link count of the file.
+ * FDH_ISUNLINKED - returns if the file has been unlinked out from under us
*
* Miscellaneous:
* FDH_FDOPEN - create a descriptor for buffered I/O
