Arguments

 

sig

   The signal to be generated.
 

sigcode

   An optional signal code, available only when not compiling in
   strict ANSI C mode. For example, signal SIGFPE-the arithmetic
   trap signal-has 10 different codes, each representing a different
   type of arithmetic trap.

   The signal codes can be represented by mnemonics or numbers. The
   arithmetic trap codes are represented by the numbers 1 to 10;
   the SIGILL codes are represented by the numbers 0 to 2. The code
   values are defined in the <signal.h> header file.
