Function cuCtxAttach

pub unsafe extern "C" fn cuCtxAttach(
    pctx: *mut CUcontext,
    flags: c_uint,
) -> CUresult

\brief Increment a context’s usage-count

\deprecated

Note that this function is deprecated and should not be used.

Increments the usage count of the context and passes back a context handle in \p *pctx that must be passed to ::cuCtxDetach() when the application is done with the context. ::cuCtxAttach() fails if there is no context current to the thread.

Currently, the \p flags parameter must be 0.

\param pctx - Returned context handle of the current context \param flags - Context attach flags (must be 0)
