The .Fa status values .Dv EXIT_SUCCESS and .Dv EXIT_FAILURE can be used to indicate successful and unsuccessful termination, respectively. .Pp Before termination it performs the following functions in the order listed: .Bl -enum -offset indent .It Call the functions registered with the .Xr atexit 3 function, in the reverse order of their registration. .It Flush all open output streams. .It Close all open streams. .It Unlink all files created with the .Xr tmpfile 3 function. .El .Pp Following this, .Fn exit calls .Xr _exit 2 . Note that typically .Xr _exit 2 only passes the lower 8 bits of .Fa status on to the parent, thus negative values have less meaning. .Sh RETURN VALUES The .Fn exit function never returns. .Sh SEE ALSO .Xr _exit 2 , .Xr atexit 3 , .Xr intro 3 , .Xr tmpfile 3 .Sh STANDARDS The .Fn exit function conforms to .St -ansiC . ft'>Commit message (Expand)Author 2009-11-18Make compat linux/linux32 msgrcv_msgarg type member of typenjoly 2008-12-09Add some padding members to linux_msqid64_ds for 32-bit archs.
