{

    /* Open the file specified by the pcFileName parameter. */
    pxFile = f_open( pcFileName, "r+" );

    /* Move the current read/write position to the position specified by
    the lTruncatePosition parameter. */
    f_seek( pxFile, lTruncatePosition, F_SEEK_SET );

    /* Truncate the file so all data past the current file position is lost. */
    if( f_seteof( pxFile ) != F_NO_ERROR )
    {
        /* The truncate failed. */
    }

    /* Finished with the file. */
