On UNIX implementations derived from AT&T UNIX, cp, ln and mv are implemented as a single program with hard-linked binaries. The behavior is selected from the path name argv [0] . This is a common technique by which closely related commands that have been packaged as a unit allow the user to specify the particular course of the intended action.
Programmers can use trampolined functions to implement tail-recursive function calls in stack-oriented programming languages. [1] In Java, trampoline refers to using reflection to avoid using inner classes, for example in event listeners. The time overhead of a reflection call is traded for the space overhead of an inner class.
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.
A screenshot of the original 1971 Unix reference page for glob – the owner is dmr, short for Dennis Ritchie.. glob() (/ ɡ l ɒ b /) is a libc function for globbing, which is the archetypal use of pattern matching against the names in a filesystem directory such that a name pattern is expanded into a list of names matching that pattern.
Windows Services for UNIX (SFU) is a discontinued software package produced by Microsoft which provided a Unix environment on Windows NT and some of its immediate successor operating-systems. SFU 1.0 and 2.0 used the MKS Toolkit ; starting with SFU 3.0, SFU included the Interix subsystem, [ 1 ] which was acquired by Microsoft in 1999 from US ...
In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
This subsystem implements only the POSIX.1 standard – also known as IEEE Std 1003.1-1990 or ISO/IEC 9945-1:1990 – primarily covering the kernel and C library programming interfaces which allowed a program written for other POSIX.1-compliant operating systems to be compiled and run under Windows NT. The Windows NT POSIX subsystem did not ...
In computing, tree is a recursive directory listing command or program that produces a depth-indented listing of files. Originating in PC- and MS-DOS, it is found in Digital Research FlexOS, [1] IBM/Toshiba 4690 OS, [2] PTS-DOS, [3] FreeDOS, [4] IBM OS/2, [5] Microsoft Windows, [6] and ReactOS. A version for Unix and Unix-like systems is also ...
