static
void
copy(
char* dstBuffer,
Blob const& srcBlob,
int position,
int length);Copy the specified length bytes starting at the specified position in the specified srcBlob to the specified dstBuffer. The behavior of this function is undefined unless 0 <= length, 0 <= position, position <= srcBlob.totalSize() - length, and dstBuffer has room for length bytes. Note that this function does not set dstBuffer[length] to 0.
