Web19 mei 2024 · 0 is returned to the child process. On the failure of a fork () system call, -1 is returned to the parent process. A child process is not created. Child Process: A child process is created by a parent process in an operating system using a fork () system call. A child process may also be known as subprocess or a subtask. WebAn isochoric process is one in which the volume is held constant, meaning that the work done by the system will be zero. It follows that, for the simple system of two dimensions, any heat energy transferred to the system externally will be absorbed as internal energy.
