WAIT(3B)							      WAIT(3B)

NAME    [Toc]    [Back]

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

SYNOPSIS    [Toc]    [Back]

     #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    [Toc]    [Back]

     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.
