HasDepth

Check to see whether device supports given pixel depth

#include <Palettes.h> Graphics Devices

short HasDepth( gdh, depth, whichFlags, flags );

GDHandle gdh ; Device whose pixel depth is being checked

short depth ; Depth being checked

short whichFlags ; Used to specify which of the gdFlags to check

short flags ; Used to specify the mode you inquire after

returns boolean, 0 if buffer has moved (error state)

HasDepth checks to see whether the device you specify supports a given

pixel depth. In the whichFlags parameter you specify which of the gdFlags set

to check; in the flags parameter you specify the value to check for. The

function returns 0 if the device does not support the mode you inquire after; if

the device does support the mode, the function returns the mode ID. For more

information, see the Slot Manager and Designing Cards and Drivers for the

Macintosh Family.

You should always test a device for a particular depth before setting the

device's depth.
