exit() does not return from the library to the program but does exit the
program.

Suppose your program has initialized the hardware on start and is supposed
to properly deinitialize the hardware before exiting.
Now it calls a library function to do data processing, and the library
just calls "exit(-1)" instead of returning an error to the app.
Your application has no chance of returning the hardware into proper state
before that exit().

It's a matter of bad programming style in library programming ;)
