[mpich2-dev] Is there any most basic send and receive functions in MPICH2?

[xiaojun Ruan]

Hi, there,
I am trying to add encryption algorithms in MPICH2. So I need to find the
most basic sending and receiving functions in MPICH2.
However, it seems that all different sending functions (Bsend, Isend, send)
call their own sending routines.
I was wondering that does an atomic sending (and receiving) operation exist
in MPICH2? If it does, where is it?

Thanks a lot.
Have a great weekend,
