Binary :: mid - Get data section from binary data block
The function returns a data section from the current binary data block beginning at position iPosition .
When the iPosition exceeds the size of the current data block, the function returns an empty data block. When iPosition is less than zero the function throws an exception.
Constant reference to a binary data block handle, which may contain binary data up to 2 GB.
Implementation overview
- Get data limited data section
Binary :: mid ( iPosition, iCount ) - Get remaining part of binary data block
Binary :: mid ( iPosition )

Get data limited data section
odaba::Binary Binary :: mid ( int32 iPosition, int32 iCount )
The function returns a data section from the current data block beginning at position iPosition .
When there are less than iCount bytes available in the data block, or when iCount is -1, the function returns remaining data after specified position. When passing 0 in iCount the function returns an empty data block.
- iPosition
- Position in collection
The position of an element in a collection is beginning with 0 for the first element.
- iCount
- Number of items
The value contains the number of items to be processed or stored in a collection.
