There is nothing such as 'name of the signal'. I guess you are refferring to the defined macros for the signal numbers.

#define SIGHUP 1 /* hangup */
#define SIGINT 2 /* interrupt (rubout) */
#define SIGQUIT 3 /* quit (ASCII FS) */

There are couple of ways to find out the description of the caught signal. One can call below functions to get the description:

void psignal(int sig, const char *s);
void psiginfo(siginfo_t *pinfo, char *s);

These functions are defined in <siginfo.h>

Coming to your second question:

As per my understanding, there is no generic function to catch all the signals. It is necessary to specify the signal you want handle.

Hope this helps.

sleep

sleep(3C)																 sleep(3C)

NAME

       sleep - suspend execution for an interval of time

SYNOPSIS

       #include <unistd.h>

       unsigned int sleep(unsigned int seconds);

       The  caller  is	suspended  from execution for the number of seconds specified by the argument. The actual suspension time may be less than
       that requested because any caught signal will terminate the sleep() following execution of that signal's catching routine.  The	suspension
       time  may  be longer than requested by an arbitrary amount because of the scheduling of other activity in the system. The value returned by
       sleep() will be the ``unslept'' amount (the requested time minus the time actually slept) if the caller incurred premature arousal  because
       of a caught signal.

       The use of the sleep() function has no effect on the action or blockage of any signal. In a multithreaded process, only the invoking thread
       is suspended from execution.
