Good evening!
I study computer engineering and recently I have programmed in C because of a project ... This same project uses two libraries (#include signal.h, #include signal.h). We use a server where all students program and use a program called putty to connect to that server.
The problem appears when I use a program external to that server (eg Visual Studios, codeblock, codelite) and when I try to compile, it gives me the kill function and also for the signals, it says that the alarms are not declared (eg SIGKILL undeclared, first use in this function).
