__default_signal_handler()

Defined in rt_misc.h, this function handles a raised signal. The default action is to print an error message and exit.

This function is not part of the C library standard, but is supported by the ARM C library as an extension.

Syntax

void __default_signal_handler(int signal, int type);

Usage

The default signal handler uses _ttywrch() to print a message and calls _sys_exit() to exit. You can replace the default signal handler by defining:

void __default_signal_handler(int signal, int type);

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.

Note

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