cuda.bindings.nvml.device_get_fbc_sessions#

cuda.bindings.nvml.device_get_fbc_sessions(intptr_t device)#

Retrieves information about active frame buffer capture sessions on a target device.

An array of active FBC sessions is returned in the caller-supplied buffer pointed at by session_info. The array element count is passed in session_count, and session_count is used to return the number of sessions written to the buffer. If the supplied buffer is not large enough to accommodate the active session array, the function returns NVML_ERROR_INSUFFICIENT_SIZE, with the element count of nvmlFBCSessionInfo_t array required in session_count. To query the number of active FBC sessions, call this function with *session_count = 0. The code will return NVML_SUCCESS with number of active FBC sessions updated in *session_count. For Maxwell ™️ or newer fully supported devices.

Parameters:

device (intptr_t) – The identifier of the target device.

Returns:

Reference in which to return the session: information.

Return type:

nvmlFBCSessionInfo_t

Note

hResolution, vResolution, averageFPS and averageLatency data for a FBC session returned in session_info may be zero if there are no new frames captured since the session started.
