Function sapnwrfc::binding::RfcGetInt2ByIndex [−] [src]

pub unsafe extern "C" fn RfcGetInt2ByIndex(
    dataHandle: DATA_CONTAINER_HANDLE, 
    index: c_uint, 
    value: *mut RFC_INT2, 
    errorInfo: *mut RFC_ERROR_INFO
) -> RFC_RC

Returns the field value as a signed two byte integer.

This function works exactly like RfcGetInt2(), the difference being that the field is addressed by its index within the structure/table/function module. The first field has index 0, last field has index n-1, the order of the fields is as defined in the ABAP DDIC.

\in dataHandle A data container (function handle, structure handle or table handle). If dataHandle is a table handle, the function will read the field value of the current row. \in index The index of the field to read. \out *value The (converted) integer value. \out *errorInfo More information in case the field does not exist or a conversion fails. \return RFC_RC
