e/Exec (operating system)

Information
has gloss	eng: The exec functions of Unix-like operating systems are a collection of functions that causes the running process to be completely replaced by the program passed as an argument to the function. As a new process is not created, the process ID (PID) does not change across an execute, but the data, heap and stack of the calling process are replaced by those of the new process.
