DESCRIPTION
       These  functions are provided in glibc as a compatibility interface =
for
       programs that make use of the historical System V signal API.  This =
API
       is  obsolete:  new applications should use the POSIX signal API (sig=
ac=E2=80=90
       tion(2), sigprocmask(2), etc.)
