-.SH DESCRIPTION
-This function will allocate, populate, and return a drmModeRes structure
-containing information about the current display configuration.
-
-The
-.I count_fbs
-and
-.I fbs
-fields indicate the number of currently allocated framebuffer objects (i.e.
-objects that can be attached to a given CRTC or sprite for display).
-
-The
-.I count_crtcs
-and
-.I crtcs
-fields list the available CRTCs in the configuration. A CRTC is simply
-an object that can scan out a framebuffer to a display sink, and contains
-mode timing and relative position information. CRTCs drive encoders, which
-are responsible for converting the pixel stream into a specific display
-protocol (e.g. MIPI or HDMI).
-
-The
-.I count_connectors
-and
-.I connectors
-fields list the available physical connectors on the system. Note that
-some of these may not be exposed from the chassis (e.g. LVDS or eDP).
-Connectors are attached to encoders and contain information about the
-attached display sink (e.g. width and height in mm, subpixel ordering, and
-various other properties).
-
-The
-.I count_encoders
-and
-.I encoders
-fields list the available encoders on the device. Each encoder may be
-associated with a CRTC, and may be used to drive a particular encoder.
-
-The min and max height fields indicate the maximum size of a framebuffer
-for this device (i.e. the scanout size limit).
-
-.SH RETURN VALUE
-Returns a drmModeRes structure pointer on success, 0 on failure.
-
-.SH REPORTING BUGS
-Bugs in this function should be reported to http://bugs.freedesktop.org under
-the "Mesa" product, with "Other" or "libdrm" as the component.
