Function lsl_sys::lsl_pull_sample_v

pub unsafe extern "C" fn lsl_pull_sample_v(
    in_: lsl_inlet, 
    buffer: *mut c_void, 
    buffer_bytes: i32, 
    timeout: f64, 
    ec: *mut i32
) -> f64

Pull a sample from the inlet and read it into a custom struct or buffer.

Overall size checking but no type checking or conversion are done. Do not use for variable-size/string-formatted streams. @param in The #lsl_inlet object to act on. @param[out] buffer A pointer to hold the resulting values. @param buffer_bytes Length of the array held by buffer in bytes, not items @param timeout The timeout for this operation, if any. Use #LSL_FOREVER to effectively disable it. It is also permitted to use 0.0 here; in this case a sample is only returned if one is currently buffered. @param[out] ec Error code: can be either no error or #lsl_lost_error (if the stream source has been lost).
@note If the timeout expires before a new sample was received the function returns 0.0; ec is not set to #lsl_timeout_error (because this case is not considered an error condition). @return The capture time of the sample on the remote machine, or 0.0 if no new sample was available. To remap this time stamp to the local clock, add the value returned by lsl_time_correction() to it.
