[ OUT origin_addr] initial address of origin buffer (choice)
[ IN origin_count] number of entries in origin buffer (nonnegative integer)
[ IN origin_datatype] datatype of each entry in origin buffer (handle)
[ IN target_rank] rank of target (nonnegative integer)
[ IN target_disp] displacement from window start to the beginning of the target buffer (nonnegative integer)
[ IN target_count] number of entries in target buffer (nonnegative integer)
[ IN target_datatype] datatype of each entry in target buffer (handle)
[ IN win] window object used for communication (handle)

Similar to MPI_PUT, except that the direction of data transfer is reversed. Data are copied from the target memory to the origin. The origin_datatype may not specify overlapping entries in the origin buffer. The target buffer must be contained within the target window, and the copied data must fit, without truncation, in the origin buffer.
