c - Use signal handler to return from a function -

Is it possible to write a signal handler that forces the program to return from a function?

For example, in the following code:

  zero myfun () {__asm ​​__ ("repeat: jmp repeat"); }   
 myfun () is an indefinite loop. I want to stop this uncertified loop and move some signals back to the main function. Is this possible?  
 Thank you.   
 
 
 inside a signal handler, set   main  in  setjmp  to prepare> Large jump .
