10.46.7 atexit ¶

POSIX specification:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/atexit.html

Gnulib module: atexit

Portability problems fixed by Gnulib:

• This function is missing on some old platforms.

Portability problems not fixed by Gnulib:

• The exit status can be incorrect for a process terminated by a signal during a call to a function registered by atexit. This is because if a signal terminates a process after exit is called or main returns, the process’s exit status is that specified by exit’s argument or by main’s return value, instead of being the exit status corresponding to the signal: z/OS 3.1.
