void __default_signal_handler(int signal, int argument)

The interface is the same as

__raise()

, but this function is only called after the C signal

handling mechanism has declined to process the signal.

A complete list of the defined signals is in

signal.h

. See Table 4-10 for those signals

that are used by the libraries.

Note

The signals used by the libraries might change in future releases of the product. See also

Table 4-18 on page 4-94 for signals handled by the

signal()

function.
