3 @deftypefn Supplemental int waitpid (int @var{pid}, int *@var{status}, int)
5 This is a wrapper around the @code{wait} function. Any ``special''
6 values of @var{pid} depend on your implementation of @code{wait}, as
7 does the return value. The third argument is unused in @libib{}.

19 to get the definition of "pid_t" before you include <sys/wait.h>. */
