       static inline hwloc_obj_t hwloc_gl_get_display_osdev_by_port_device (hwloc_topology_t
           topology, unsigned port, unsigned device)

       static inline int hwloc_gl_get_display_by_osdev (hwloc_topology_t topology , hwloc_obj_t
           osdev, unsigned *port, unsigned *device)

Detailed Description

       This interface offers ways to retrieve topology information about OpenGL displays.

       Only the NVIDIA display locality information is currently available, using the NV-CONTROL
       X11 extension and the NVCtrl library.

Function Documentation

   static inline int hwloc_gl_get_display_by_osdev (hwloc_topology_t topology, hwloc_obj_tosdev,
       unsigned *port, unsigned *device) [static]
       Get the OpenGL display port and device corresponding to the given hwloc OS object. Return
       the OpenGL display port (server) in port and device (screen) in screen that correspond to
       the given hwloc OS device object. Return -1 if there is none.

       The topology topology does not necessarily have to match the current machine. For instance
       the topology may be an XML import of a remote host. I/O devices detection and the GL
       component must be enabled in the topology.

   static inline hwloc_obj_t hwloc_gl_get_display_osdev_by_name (hwloc_topology_ttopology, const
       char *name) [static]
       Get the hwloc OS device object corresponding to the OpenGL display given by name. Return
       the OS device object describing the OpenGL display whose name is name, built as
       ':port.device' such as ':0.0' . Return NULL if there is none.

       The topology topology does not necessarily have to match the current machine. For instance
       the topology may be an XML import of a remote host. I/O devices detection and the GL
       component must be enabled in the topology.

       Note:
           The corresponding PCI device object can be obtained by looking at the OS device parent
           object.

   static inline hwloc_obj_t hwloc_gl_get_display_osdev_by_port_device (hwloc_topology_ttopology,
       unsignedport, unsigneddevice) [static]
       Get the hwloc OS device object corresponding to the OpenGL display given by port and
       device index. Return the OS device object describing the OpenGL display whose port
       (server) is port and device (screen) is device. Return NULL if there is none.

       The topology topology does not necessarily have to match the current machine. For instance
       the topology may be an XML import of a remote host. I/O devices detection and the GL
       component must be enabled in the topology.

       Note:
           The corresponding PCI device object can be obtained by looking at the OS device parent
           object.
