BloombergLP::bdlbb::BlobUtil::prependDataBufferIfValid

Insert the specified move‐insertable buffer before the beginning of the specified dest if neither the resulting total size of dest nor its resulting total number of buffers exceeds INT_MAX. Return 0 on success, and a non‐zero value (with no effect) otherwise. The length of the dest is incremented by the length of the prepended buffer. In case of success the buffer is left in a valid but unspecified state.
