A MEX file is a type of computer file that provides an interface between MATLAB or Octave and functions written in C, C++ or Fortran.It stands for "MATLAB executable". When compiled, MEX files are dynamically loaded and allow external functions to be invoked from within MATLAB or Octave as if they were built-in functions.
A File Control Block (FCB) is a file system structure in which the state of an open file is maintained. A FCB is managed by the operating system, but it resides in the memory of the program that uses the file, not in operating system memory.
A DCB is one of the many control blocks used in these operating systems. A control block is a data area with a predefined structure, very similar to a C struct, but typically only related to system's functions. A DCB may be compared to a FILE structure in C, but it is much more complex, offering many more options for various access methods.
file must be able to determine the types directory, FIFO, socket, block special file, and character special file; zero-length files are identified as such; an initial part of file is considered and file is to use position-sensitive tests; the entire file is considered and file is to use context-sensitive tests; the file is identified as a data file
PHP provides a file-based locking [17] as well as a Mutex class in the pthreads extension. [18] Python provides a low-level mutex mechanism with a Lock class from the threading module. [19] The ISO/IEC Fortran standard (ISO/IEC 1539-1:2010) provides the lock_type derived type in the intrinsic module iso_fortran_env and the lock/unlock ...
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte . A large value is often expressed with a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ).
In computer programming, a function (also procedure, method, subroutine, routine, or subprogram) is a callable unit [1] of software logic that has a well-defined interface and behavior and can be invoked multiple times.
Note that in addition to the below table, block capabilities can be implemented below the file system layer in Linux (LVM, integritysetup, cryptsetup) or Windows (Volume Shadow Copy Service, SECURITY), etc.
