* SEGGER_RTT_WriteSkipNoLock
*
* Function description
* Stores a specified number of characters in SEGGER RTT

* SEGGER_RTT_WriteSkipNoLock does not lock the application and
* skips all data, if the data does not fit into the buffer.
*
* Parameters
* BufferIndex Index of "Up"-buffer to be used (e.g. 0 for "Terminal").
* pBuffer Pointer to character array. Does not need to point to a \0 terminated string.
* NumBytes Number of bytes to be stored in the SEGGER RTT control block.
* MUST be > 0!!!
* This is done for performance reasons, so no initial check has do be done.
*
* Return value
* 1: Data has been copied
* 0: No space, data has not been copied
*
* Notes
* (1) If there is not enough space in the "Up"-buffer, all data is dropped.
* (2) For performance reasons this function does not call Init()
* and may only be called after RTT has been initialized.
* Either by calling SEGGER_RTT_Init() or calling another RTT API function first.
