+========
+
+``#include <xf86drm.h>``
+
+``#include <xf86drmMode.h>``
+
+``drmModeResPtr drmModeGetResources(int fd);``
+
+Description
+===========
+
+``drmModeGetResources`` allocates, populates, and returns a drmModeRes
+structure containing information about the current display
+configuration. The structure contains the following fields:
+
+::
+
+   typedef struct _drmModeRes {
+       int count_fbs;
+       uint32_t *fbs;
+
+       int count_crtcs;
+       uint32_t *crtcs;
+
+       int count_connectors;
+       uint32_t *connectors;
+
+       int count_encoders;
+       uint32_t *encoders;
+
+       uint32_t min_width, max_width;
+       uint32_t min_height, max_height;
+   } drmModeRes, *drmModeResPtr;
+
+The *count_fbs* and *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 *count_crtcs* and *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 *count_connectors* and *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 *count_encoders* and *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_\** fields indicate the maximum size of a framebuffer
+for this device (i.e., the scanout size limit).
+
+Return Value
+============
+
+``drmModeGetResources`` returns a drmModeRes structure pointer on
+success, NULL on failure. The returned structure must be freed with
+**drmModeFreeResources**\ (3).
