API RESTRICTIONS

The function or functions documented here may not be used safely in all application contexts with all APIs provided in the ChorusOS 5.0 product.

See API(5FEA) for details.

DESCRIPTION

Calling atexit() adds the func() function to a list of functions to be called, without argument, on normal termination of the program. Normal termination occurs either by a call to exit(3STDC) or by a return from main.

RETURN VALUES

The atexit() function returns 0 if the registration succeeded, non-zero if it failed.

NOTES

atexit() is reentrant. The related exit(3STDC) processing requires special attention with regard to concurrent execution.
