In other words, file locks lock out other file lockers only, not I/O. Two kinds of locks are offered: shared locks and exclusive locks. In the case of fcntl, different kinds of locks may be applied to different sections (byte ranges) of a file, or else to the whole file. Shared locks can be held by multiple processes at the same time, but an ...
The Range Lock Sector must exist in files greater than 2GB in size, and must not exist in files smaller than 2GB. The Range Lock Sector must contain the byte range 0x7FFFFF00 to 0x7FFFFFFF in the file. This area is reserved by Microsoft's COM implementation for storing byte-range locking information for concurrent access.
An OST is a dedicated filesystem that exports an interface to byte ranges of file objects for read/write operations, with extent locks to protect data consistency. An MDT is a dedicated filesystem that stores inodes, directories, POSIX and extended file attributes , controls file access permissions/ ACLs , and tells clients the layout of the ...
Microsoft compressed file in Quantum format, used prior to Windows XP. File can be decompressed using Extract.exe or Expand.exe distributed with earlier versions of Windows. After compression, the last character of the original filename extension is replaced with an underscore, e.g. ‘Setup.exe’ becomes ‘Setup.ex_’. 46 4C 49 46: FLIF: 0 flif

the byte-range advisory Network Lock Manager (NLM) protocol (added to support UNIX System V file locking APIs) the remote quota-reporting (RQUOTAD) protocol, which allows NFS users to view their data-storage quotas on NFS servers; NFS over RDMA, an adaptation of NFS that uses remote direct memory access (RDMA) as a transport [12] [13]
DCE/DFS is believed to be the world's only distributed filesystem that correctly implements the full POSIX filesystem semantics, including byte range locking. [ 7 ] DCE/DFS was sufficiently reliable and stable to be utilised by IBM to run the back-end filesystem for the 1996 Olympics web site, seamlessly and automatically distributed and edited ...
For example, the ISO 6429 control function "Control Sequence Introducer", which can be represented using an escape sequence, is followed by zero or more bytes in the range 0x30–0x3F, then zero or more bytes in the range 0x20–0x2F, then by a single byte in the range 0x40–0x7E, the entire sequence being called a "control sequence".
