Action

Retrieves the value of a specified integer field within a typed buffer. This function can be used to manipulate any of the following predefined buffer types:

FML, FML32

Include file

TUXEDO.bdh

Syntax

TuxGetInt(in hBuffer  : number,
          in nFieldId : number
          in nIndex   : number optional): number;

Return value

Integer value retrieved from the typed buffer.

Parameter	Description
hBuffer	Typed buffer allocated with TuxGetBuffer or Tux_tpalloc.
nFieldId	Identifier specifying a field of the typed buffer
nIndex	Array index (optional). This parameter has to be passed to the function if the field identifier specifies an integer array

Example

const
  ID_NUMBERS :=  8;
  ID_SUM     := 16; 

dcltrans
  transaction TMain
  var 
    hBuffer, olen, nResult: number;
  begin 
    Tux_tpbegin(30, 0); 

    // allocate buffer
    TuxGetBuffer(hBuffer, "FML", NULL, 1024);
 
    // store two integer value in buffer
    TuxSetInt(hBuffer, ID_NUMBERS, 8, 1);
    TuxSetInt(hBuffer, ID_NUMBERS, 4, 2); 

    // calculate sum
    Tux_tpcall("SUM", hBuffer, 0, hBuffer, olen, TPNOFLAGS); 

    // retrieve result
    nResult := TuxGetInt(hBuffer, ID_SUM);
    Tux_tpcommit(0);
  end TMain;
