      [edit]Program termination

      The following functions manage program termination and resources cleanup.

      Defined in header<stdlib.h>
      causes abnormal program termination (without cleaning up)
      (function)[edit]
      causes normal program termination with cleaning up
      (function)[edit]
      causes normal program termination without completely cleaning up
      (function)[edit]
      (C99)
      		 causes normal program termination without cleaning up
      (function)[edit]
      registers a function to be called onexit() invocation
      (function)[edit]
      registers a function to be called onquick_exit invocation
      (function)[edit]
      indicates program execution execution status
      (macro constant)[edit]

      [edit]Unreachable control flow

      Defined in header<stddef.h>
      marks unreachable point of execution
      (function macro)[edit]

      [edit]Communicating with the environment

      Defined in header<stdlib.h>
      calls the host environment's command processor
      (function)[edit]
      access to the list of environment variables
      (function)[edit]

      [edit]Memory alignment query

      Defined in header<stdlib.h>
      queries the alignment of a pointer value
      (function)[edit]

      [edit]Signals

      Several functions and macro constants for signal management are provided.

      Defined in header<signal.h>
      sets a signal handler for particular signal
      (function)[edit]
      runs the signal handler for particular signal
      (function)[edit]
      the integer type that can be accessed as an atomic entity from an asynchronous signal handler
      (typedef)
      defines signal handling strategies
      (macro constant)[edit]
      error was encountered
      (macro constant)[edit]
      Signal types
      defines signal types
      (macro constant)[edit]

      [edit]Non-local jumps

      Defined in header<setjmp.h>
      saves the context
      (function macro)[edit]
      jumps to specified location
      (function)[edit]
      Types
      execution context type
      (typedef)[edit]
