Difference between signal() and sigaction() function

Hello Sir...Could you tell me the KEY difference between signal and sigaction functions....Kindly consider the following sample program which is using signal function...
Expand|Select|Wrap|Line Numbers
  1. #include <signal.h>
  2. void mysighandler(void);
  3. int main ()
  4. {
  5.     signal(SIGINT,mysighandler);
  6.     char ch;
  7.     while(1) {
  8.         ch=getchar();
  9.         putchar(ch);
  10.     }
  11. }
  12. void mysighandler(void);
  13. {
  14.     printf("interrrupt signal recieved\n");
  15. }
  16.  
The above main function goes into infinite loop ...when I press ctrl-C my signal handler is getting executed..upto this is fine..
But what difference it makes when I use sigaction() system call in the above program...
I would be thankful if you help me...
