+This function will process outstanding DRM events on

+Returns 0 on success, or if there is no data to read from the file descriptor.

+.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.
