#pragma fini

#pragma fini (identifier [, identifier]...)

Use fini to mark identifier as a finalization function. Such functions are expected to be of type void, to accept no arguments, and to be called either when a program terminates under program control or when the containing shared object is removed from memory. As with initialization functions, finalization functions are executed in the order processed by the link editor.

In a source file, the functions specified in #pragma fini are executed after the static destructors in that file. You must declare the identifiers before using them in the pragma.
