Hi all, I am using ptrace to keep track of clone syscalls in a program. However, I found that the traced syscall cant be paired. for example, there are some syscalls that have entry, but without exit showing up in the traced sequences. So, is there anyway to distinguish the entry and exit of a...

bsetroot

bsetroot(1)						      General Commands Manual						       bsetroot(1)

NAME

       bsetroot - blackbox utility to change root window appearance

SYNOPSIS

       bsetroot -help
       bsetroot [ -display display ] -solid color
       bsetroot [ -display display ] -mod x y -fg color -bg color
       bsetroot [ -display display ] -gradient texture -from color -to color

DESCRIPTION

       Bsetroot  is a utility that can control the appearance of the root window in three ways: Either give it a solid color, or write a two color
       modula pattern to it, or render a gradient texture, based on two different colors.

       Bsetroot resembles xsetroot(1) in this functionality but it supports multiple screen displays, and gradient textures the same way as Black-
       box does.  It doesn't handle cursors etc.  Bsetroot is part of the Blackbox package.

OPTIONS

       Bsetroot operates in three ways, you must choose one of the first 3 options:

       -solid color
	      Sets the root window to specified color.

       -mod x y
	      Creates a modula pattern. You must specify -bg and -fg colors.

       -gradient texturestring
	      Renders  the specified texture string to the root window.  For possible texture strings, please refer to blackbox(1).  You must also
	      specify both a -from and a -to color.

       -display display
	      Tells Bsetroot to connect to the specified display.

       -bg, -background color
	      Background color.  Needed for -mod patterns.

       -fg, -foreground color
	      Foreground color.  Needed for -mod patterns.

       -from color
	      Start color for rendering textures.  Needed for -gradient operation mode.

       -to color
	      Ending color for rendering textures.  Needed for -gradient operation mode.

       -help  Prints version info and short help text.
