4.5 __default_signal_handler()
Defined in rt_misc.h, the __default_signal_handler() 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 the ARM® C library supports it as an extension.
Syntax
int __default_signal_handler(int signal, int type);
Usage
The default signal handler returns a nonzero value to indicate that the caller has to arrange for the program to exit. You can replace the default signal handler by defining:
int __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.
