NAME
    CloseIFF -- Close an IFF context.

SYNOPSIS
    CloseIFF (iff)
              a0

    struct IFFHandle *iff;

FUNCTION
    Completes an IFF read or write operation by closing the IFF context
    established for this IFFHandle struct.  The IFFHandle struct itself
    is left ready for re-use and a new context can be opened with
    OpenIFF().  This function can be used for cleanup if a read or write
    fails partway through.

    As part of its cleanup operation, CloseIFF() calls the client-
    supplied stream hook vector.  The IFFStreamCmd packet will be set
    as follows:

            sc_Command:     IFFCMD_CLEANUP
            sc_Buf:         (Not applicable)
            sc_NBytes:      (Not applicable)

    This operation is NOT permitted to fail;  any error code returned
    will be ignored (best to return 0, though).  DO NOT write to this
    structure.

INPUTS
    iff     - pointer to IFFHandle struct previously opened with
              OpenIFF().
