This type is a structure to describe a buffer. The user should make sure that this structure is initialized to zero. The available fields of this structure are:
This is either 0 for no information available or indicates the allocated length of the buffer.
This is the offset into the buffer.
This is the valid length of the buffer starting at
This is the address of the buffer.
