BloombergLP::bdlbb::Blob::insertBuffer

Insert the specified move‐insertable buffer at the specified index in this blob. Increment the length of this blob by the size of buffer if buffer is inserted before the logical end of this blob. The length of this blob is if inserting at a position following all data buffers (e.g., inserting into an empty blob or inserting a buffer to increase capacity); in that case, the blob length must be changed by an explicit call to setLength. Buffers at index and higher positions (if any) are shifted up by one index position. The buffer is left in a valid but unspecified state. The behavior is undefined unless 0 <= index <= numBuffers() and neither the total size of the resulting blob nor its total number of buffers exceeds INT_MAX.
