Function rcudnn_sys::cudaStreamGetCaptureInfo

\brief Query capture status of a stream

Note there is a later version of this API, ::cudaStreamGetCaptureInfo_v2. It will supplant this version in 12.0, which is retained for minor version compatibility.

Query the capture status of a stream and get a unique id representing the capture sequence over the lifetime of the process.

If called on ::cudaStreamLegacy (the “null stream”) while a stream not created with ::cudaStreamNonBlocking is capturing, returns ::cudaErrorStreamCaptureImplicit.

A valid id is returned only if both of the following are true:

• the call returns ::cudaSuccess
• captureStatus is set to ::cudaStreamCaptureStatusActive

\param stream - Stream to query \param pCaptureStatus - Returns the stream’s capture status \param pId - Returns the unique id of the capture sequence

\return ::cudaSuccess, ::cudaErrorStreamCaptureImplicit \notefnerr
