ignored; programs should use <code>signal (SIGALRM, SIG_DFL)</code> if
it is important to ensure the alarm will fire.
Use of this function in multi-threaded applications is not advised.
This function is missing on some platforms:
mingw (2011), MSVC 9.
This function is conditionally declared in the non-standard
@code{<io.h>} header on some platforms:
mingw (2012 or newer).
