  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. Higher-level languages usually provide one call named exec.

  3. System call - Wikipedia

    en.wikipedia.org/wiki/System_call

    The actual system call does transfer control to the kernel (and is more implementation-dependent and platform-dependent than the library call abstracting it). For example, in Unix-like systems, fork and execve are C library functions that in turn execute instructions that invoke the fork and exec system calls.

  4. Fork–exec - Wikipedia

    en.wikipedia.org/wiki/Fork–exec

    In some cases the two continue to run the same binary, but often one (usually the child) switches to running another binary executable using the exec() system call. When a process forks, a complete copy of the executing program is made into the new process. This new process is a child of the parent process, and has a new process identifier (PID).

  6. fork (system call) - Wikipedia

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

    For a process to start the execution of a different program, it first forks to create a copy of itself. Then, the copy, called the "child process", calls the exec system call to overlay itself with the other program: it ceases execution of its former program in favor of the other. The fork operation creates a separate address space for the ...

    en.wikipedia.org/wiki/Kexec

    kexec (kernel execute), analogous to the Unix/Linux kernel call exec, is a mechanism of the Linux kernel that allows booting of a new kernel from the currently running one. Details [ edit ]

  9. Chain loading - Wikipedia

    en.wikipedia.org/wiki/Chain_loading

    In Unix (and in Unix-like operating systems), the exec() system call is used to perform chain loading. The program image of the current process is replaced with an entirely new image, and the current thread begins execution of that image. The common data area comprises the process' environment variables, which are preserved across the system call.
