Hi guys, I just tried the die function inside main.c
It did not get called when I ctrl + c a running make process. Please help here. Also, fatal error handler in commands.C gets called multiple times. I believe it is getting called for each parallel make process the parent has invoked. Helpless now, need to find answer to below questions - 1) why the die() function is not getting called after a ctrl+c ? 2) why I am not able to printf anything in fatal error handler in commands.c ? I do printf but it doesn’t print on the screen. The stdout is gone? I tried running some command using system call and it ran means the control is definitely doing inside fatal error handler. 3) I basically want to know a way in which I should be able to execute a piece of code when main exits. Where should I put it? Just a note - the makefiles are not normal. They are trapping sigint using TRAP command in gnumakefile. Please help guys.
