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

pub unsafe extern "C" fn RfcGetNumByIndex(
    dataHandle: DATA_CONTAINER_HANDLE, 
    index: c_uint, 
    charBuffer: *mut RFC_NUM, 
    bufferLength: c_uint, 
    errorInfo: *mut RFC_ERROR_INFO
) -> RFC_RC

Returns the value of the specified field as num-char array (digits only).

This function works exactly like RfcGetNum(), 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. \out *charBuffer A pre-allocated buffer, which will receive the (converted) field value. \in bufferLength Size of the buffer in RFC_CHARs. \out *errorInfo Field doesn't exist, cannot be converted to numc, etc. \return RFC_RC
