Moved to C process control functions

C program control operations are a group of functions in the standard library of the C programming language implementing basic program control operations.[1][2]

Overview of functions

The program control functions are defined in the stdlib.h header (cstdlib header in C++).

Terminating a program
  • abort - causes abnormal program termination (without cleaning up)
  • exit - causes normal program termination with cleaning up
  • _Exit - causes normal program termination without cleaning up
  • atexit - registers a function to be called on exit() invocation
Communicating with the environment
  • getenv - accesses the list of the environment variables
  • system - calls the host environment's command processor
