wait(3B)

NAME
     wait, wait3 - wait for child processes to stop or terminate

SYNOPSIS
     #include <sys/types.h>
     #include <sys/wait.h>
     #include <sys/resource.h>

     int wait ();

     int wait3 ();

     To use either of these routines you must either

     1) #define _BSD_COMPAT before including <sys/wait.h>, or

     2) specify it in the compile command or makefile:

          cc -D_BSD_COMPAT -o prog prog.c


DESCRIPTION
     These two routines are fully described in wait(2).  When BSD
     compatibility mode is enabled (via the definition of _BSD_COMPAT) the
     only change is in the prototype declaration of these routines in
     sys/wait.h.  Historically, many BSD derived programs pass as the status
     pointer, a pointer to a union wait, rather than a pointer to int.  Since
     these programs would not properly compile if prototyping was in effect,
     when BSD compatibility mode is enabled, no prototypes are declared.
