Specifies the class of the screen.

Specifies the visual mask value.
Returns the matched visual information.

The XMatchVisualInfo function returns the visual information for a visual that matches the specified depth and class for a screen. Because multiple visuals that match the specified depth and class can exist, the exact visual chosen is undefined. If a visual is found, XMatchVisualInfo returns nonzero and the information on the visual to vinfo_return. Otherwise, when a visual is not found, XMatchVisualInfo returns zero.
The XVisualIDFromVisual function returns the visual ID for the specified visual type.
