Function soapysdr_sys::SoapySDRDevice_getNumDirectAccessBuffers

pub unsafe extern "C" fn SoapySDRDevice_getNumDirectAccessBuffers(
    device: *mut SoapySDRDevice,
    stream: *mut SoapySDRStream
) -> usize

How many direct access buffers can the stream provide? This is the number of times the user can call acquire() on a stream without making subsequent calls to release(). A return value of 0 means that direct access is not supported.

\param device a pointer to a device instance \param stream the opaque pointer to a stream handle \return the number of direct access buffers or 0
