/* @deftypefn Supplemental int waitpid (int @var{pid}, int *@var{status}, int) This is a wrapper around the @code{wait} function. Any ``special'' values of @var{pid} depend on your implementation of @code{wait}, as does the return value. The third argument is unused in @libib{}. @end deftypefn */ #ifdef HAVE_CONFIG_H #include "config.h" #endif /* On some systems (such as WindISS), you must include <sys/types.h> to get the definition of "pid_t" before you include <sys/wait.h>. */ #include <sys/types.h> #ifdef HAVE_SYS_WAIT_H #include <sys/wait.h> #endif pid_t waitpid (pid, stat_loc, options) pid_t pid; int *stat_loc, options; { for (;;) { int wpid = wait(stat_loc); if (wpid == pid || wpid == -1) return wpid; } }
