  2. exec (system call) - Wikipedia

    en.wikipedia.org/wiki/Exec_(system_call)

    Standard names of such functions in C are execl, execle, execlp, execv, execve, and execvp (see below), but not "exec" itself. The Linux kernel has one corresponding system call named "execve", whereas all aforementioned functions are user-space wrappers around it.

  3. Compile-time function execution - Wikipedia

    en.wikipedia.org/wiki/Compile-time_function...

    In C++11, this technique is known as generalized constant expressions (constexpr). [2] C++14 relaxes the constraints on constexpr – allowing local declarations and use of conditionals and loops (the general restriction that all data required for the execution be available at compile-time remains).

  4. Wrapper function - Wikipedia

    en.wikipedia.org/wiki/Wrapper_function

    A helper function is a function which groups parts of computation by assigning descriptive names and allowing for the reuse of the computations. [6] Although not all wrappers are helper functions, all helper functions are wrappers, and a notable use of helper functions—grouping frequently utilized operations—is in dynamic binary translation, in which helper functions of a particular ...

  5. System call - Wikipedia

    en.wikipedia.org/wiki/System_call

    A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.

  6. Fork–exec - Wikipedia

    en.wikipedia.org/wiki/Fork–exec

    fork() is the name of the system call that the parent process uses to "divide" itself ("fork") into two identical processes. After calling fork(), the created child process is an exact copy of the parent except for the return value of the fork() call.

  7. a.out - Wikipedia

    en.wikipedia.org/wiki/A.out

    a.out is a file format used in older versions of Unix-like computer operating systems for executables, object code, and, in later systems, shared libraries.This is an abbreviated form of "assembler output", the filename of the output of Ken Thompson's PDP-7 assembler. [1]

  8. Nix (package manager) - Wikipedia

    en.wikipedia.org/wiki/Nix_(package_manager)

    New files in the Nix store are created through "derivations". A derivation is a persistent data structure that specifies an executable, arguments and environment variables for its invocation (see execve), and other files to be read from the Nix store. The executable is then run in a sandbox that prohibits access to anything but the explicitly ...

  9. Function (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Function_(computer...

    This function requires C++ – would not compile as C. It has the same behavior as the preceding example but passes the actual parameter by reference rather than passing its address. A call such as addTwo(v) does not include an ampersand since the compiler handles passing by reference without syntax in the call.
