    start_section: c_int, 
    mh: *mut grib_multi_handle
) -> c_int

Append the sections starting with start_section of the message pointed by h at the end of the multi-field handle mh. Remember always to delete the multi handle when it is not needed anymore to avoid memory leaks.

@param h : The handle from which the sections are copied. @param start_section : section number. Starting from this section all the sections to the end of the message will be copied. @param mh : The multi field handle on which the sections are appended. @return 0 if OK, integer value on error
