SCREENBLANK(1) BSD General Commands Manual SCREENBLANK(1) NAME
screenblank -- screen saver daemon for wscons and FBIO machines SYNOPSIS
screenblank [-k | -m] [-d inactivity-timeout] [-e wakeup-delay] [-f framebuffer] [-i input-device] screenblank {-b | -u} DESCRIPTION
screenblank disables the framebuffer if the keyboard and mouse are idle for a period of time, and re-enables the framebuffer when keyboard or mouse activity resumes. When killed with a SIGINT, SIGHUP, or SIGTERM, screenblank will re-enable the framebuffer. The pid can be found in the file /var/run/screenblank.pid. The options are as follows: -b Overriding the other options, simply try (once) to blank the framebuffer, then exit. -d inactivity-timeout Wait the number of seconds specified by inactivity-timeout, expressed in the format ``xxx.xxx'', before disabling the framebuffer due to inactivity. The default is 600 seconds (10 minutes). -e wakeup-delay Wait the number of seconds specified by wakeup-delay, expressed in the format ``xxx.xxx'', before re-enabling the framebuffer once activity resumes. The default is .25 seconds. -f framebuffer Use the framebuffer device framebuffer instead of the default /dev/fb. -i input-device Add input-device to the list of devices to monitor for activity. -k Do not check the keyboard for activity. -m Do not check the mouse for activity. -u Overriding the other options, simply try (once) to unblank the framebuffer, then exit. Note that the -k and -m flags are mutually exclusive. FILES
/dev/kbd The keyboard device. /dev/mouse The mouse device. /dev/console The console device. /dev/fb The default framebuffer. /dev/wskbd The keyboard for wscons machines. /dev/wsmouse The mouse device for wscons machines. /dev/ttyE0 The console device for wscons machines. /var/run/screenblank.pid File containing the pid of screenblank.

GLBINDFRAMEBUFFER(3G) OpenGL 3.3 GLBINDFRAMEBUFFER(3G) NAME
glBindFramebuffer - bind a framebuffer to a framebuffer target C SPECIFICATION
void glBindFramebuffer(GLenum target, GLuint framebuffer); PARAMETERS
target Specifies the framebuffer target of the binding operation. framebuffer Specifies the name of the framebuffer object to bind. DESCRIPTION
glBindFramebuffer binds the framebuffer object with name framebuffer to the framebuffer target specified by target. target must be either GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER or GL_FRAMEBUFFER. If a framebuffer object is bound to GL_DRAW_FRAMEBUFFER or GL_READ_FRAMEBUFFER, it becomes the target for rendering or readback operations, respectively, until it is deleted or another framebuffer is bound to the corresponding bind point. Calling glBindFramebuffer with target set to GL_FRAMEBUFFER binds framebuffer to both the read and draw framebuffer targets. framebuffer is the name of a framebuffer object previously returned from a call to glGenFramebuffers(), or zero to break the existing binding of a framebuffer object to target. ERRORS
GL_INVALID_ENUM is generated if target is not GL_DRAW_FRAMEBUFFER, GL_READ_FRAMEBUFFER or GL_FRAMEBUFFER. GL_INVALID_OPERATION is generated if framebuffer is not zero or the name of a framebuffer previously returned from a call to glGenFramebuffers(). SEE ALSO
