Description.  This method sets the position within the blob at which to read or write data.

Signature. 

int setPos

Parameters.  The setPos() method takes a single parameter pos (an unsigned 64-bit integer), which is the position for reading or writing data. The value of pos must be between 0 and the blob's current length.

Important

Sparse blobs are not supported in the NDB API; in other words, there can be no unused data positions within a blob.
