DBXHANG(1)							    DBXHANG(1)

NAME    [Toc]    [Back]

     dbxhang - start a process without really starting it

SYNOPSIS    [Toc]    [Back]

     dbxhang  object-file

DESCRIPTION    [Toc]    [Back]

     dbxhang starts a program running by doing a fork(2) and  exec(2), leaving
     the program stopped before	executing its first instruction.

     This is useful when a program to be debugged does unusual things with tty
     characteristics, or which is sensitive to the <Interrupt> character and
     you don't want any	<Interrupt> in the dbx command window sent to the
     program to	be debugged.

     Use dbxhang on the	program	to be debugged in one window and intercept the
     stopped program with dbx -p or dbx	-P from	a different window.  In	the
     dbx session window, continue the program (after setting any breakpoints
     desired) with the cont command: the run command is	not usable on a
     program intercepted with -p or -P.

     Example:

	 dbxhang myprog	myargument1 myargument2
	 (and, from another window)
	 dbx -P	myprog
	 stop in main
	 cont
