hwlocality_gl - Interoperability with OpenGL displays

       Generated automatically by Doxygen for Hardware Locality (hwloc) from the source code.

Hardware Locality (hwloc)                        Version 2.12.0                                 hwlocality_gl(3)

       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.

inthwloc_gl_get_display_by_osdev(hwloc_topology_ttopology,hwloc_obj_tosdev,unsigned*port,unsigned*device)[inline]
       Get the OpenGL display port and device corresponding to the given hwloc OS object. Retrieves the OpenGL
       display port (server) in port and device (screen) in screen that correspond to the given hwloc OS device
       object.

       Returns
           0 on success.

           -1 if none could be found.

       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.

   hwloc_obj_thwloc_gl_get_display_osdev_by_name(hwloc_topology_ttopology,constchar*name)[inline]
       Get the hwloc OS device object corresponding to the OpenGL display given by name.

       Returns
           The hwloc OS device object describing the OpenGL display whose name is name, built as ':port.device'
           such as ':0.0' .

           NULL if none could be found.

       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 (unless
           PCI devices are filtered out).

   hwloc_obj_thwloc_gl_get_display_osdev_by_port_device(hwloc_topology_ttopology,unsignedport,unsigneddevice)[inline]
       Get the hwloc OS device object corresponding to the OpenGL display given by port and device index.

       Returns
           The hwloc OS device object describing the OpenGL display whose port (server) is port and device
           (screen) is device.

           NULL if none could be found.

       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.
