# xxxCloseStream()

This function is required when terminating processing for document headers, footers, footnotes, and endnotes.

## Syntax

    int pascal _export xxxCloseStream(
        void    *pCFContext,
        int      type)

## Arguments

`pCFContext` | A pointer to the global context structure for the custom reader.
`type` | An integer identifying a specific header, footer, footnote, or endnote. Options are defined in `kvcfsr.h`.

## Returns

- Upon success, `KVERR_Success`.
- Upon error, a non-zero error code.

## Discussion

Prior to exiting this function, the previously saved values in the global context structure must be restored. This ensures that processing of the main body resumes with the correct document state.
