SetOutputStream Method

The stream to which the class will write the JSON.

Syntax

ANSI (Cross Platform)
int SetOutputStream(IPWorksMQStream* sOutputStream);

Unicode (Windows)
INT SetOutputStream(IPWorksMQStream* sOutputStream);
#define MID_JSON_SETOUTPUTSTREAM 23

IPWORKSMQ_EXTERNAL int IPWORKSMQ_CALL IPWorksMQ_JSON_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method sets the stream to which output will be written when writing data.

Output Properties

The class will determine the destination of the output based on which properties are set.

The order in which the output properties are checked is as follows:

  • OutputFile
  • OutputData: The output data is written to this property if no other destination is specified.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
