How can I deal with Segmentation fault - sigsegv ?

[Frank Fock]

Hi,

The segmentation fault is most likely a programmin error. Run the program in
a debugger and find out the cause.(May be it's dereferencing a null pointer?).

signal() is a system function to register a function to be called when certain
events (signals) occur.

Best regards,
Frank
