rX_SysInterlockExchange usage?

Hi,

I found there are some rcX APIs given in header file but not listed in rcX_API.pdf...for example rX_SysInterlockExchange(). Would you give some description on this function? And, could you give a more detail document on those functions that not listed in previous version rcX_API.pdf (2008/01/23).

Thanks.

Hi Yu Zhang,

the function rX_SysInterlockExchange() is used, to set a variable to a specified value as an atomic operation.

This will lock the variable between the read and write operation to it.
