2.2.4 File Chunk Reference

  • Article

A file chunk reference specifies a reference to data in the file. Each file chunk reference contains an stp field and a cb field. The stp field is a stream pointer that specifies the offset, in bytes, from the beginning of the file where the referenced data is located. The cb field specifies the size, in bytes, of the referenced data. The sizes, in bytes, of the stp and cb fields are specified by the structures in this section.

Special values:

fcrNil: Specifies a file chunk reference where all bits of the stp field are set to 1, and all bits of the cb field are set to zero.

fcrZero: Specifies a file chunk reference where all bits of the stp and cb fields are set to zero.
