Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The exit and _exit functions terminate the calling process. The
     exit function first calls, in "last in, first out" order, the
     functions registered by atexit and onexit. It then flushes all
     file buffers before terminating the process.
 
     The _exit function terminates the process without processing
     atexit or onexit functions or flushing stream buffers.
 
     The <status> value is typically set to 0 to indicate a normal exit
     and set to some other value to indicate an error.
 
     Although the exit and _exit calls do not return a value, the
     low-order byte of <status> is made available to the waiting parent
     process, if one exists, after the calling process exits. The
     <status> value is available to the operating-system batch command
     ERRORLEVEL.
 
     The behavior of the exit, _exit, _cexit, and _c_exit functions is
     as follows:
 
     Function     Action
 
     exit         Performs complete C library termination procedures,
                  terminates the process, and exits with the supplied
                  status code
 
     _exit        Performs "quick" C library termination procedures,
                  terminates the process, and exits with the supplied
                  status code
 
     _cexit       Performs complete C library termination procedures
                  and returns to caller, but does not terminate
                  the process
 
     _c_exit      Performs "quick" C library termination procedures and
                  returns to caller, but does not terminate the process
 
     Return Value
 
     None.
