SetOutputStream Method
Sets the stream to which output data should be written.
Syntax
ANSI (Cross Platform) int SetOutputStream(CloudKeysStream* sOutputStream); Unicode (Windows) INT SetOutputStream(CloudKeysStream* sOutputStream);
#define MID_GOOGLEKMS_SETOUTPUTSTREAM 23 CLOUDKEYS_EXTERNAL int CLOUDKEYS_CALL CloudKeys_GoogleKMS_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
This method sets the stream to which data output from a successful cryptographic operation should be written.
Passing a non-null value for OutputStream will cause the OutputFile property to be cleared. Similarly, setting OutputFile to a non-empty value will discard any stream set using this method.
Input Sources & Output Destinations
The class automatically determines the source and destination of the input and output based on which properties are set.
The order in which the input properties are checked is as follows:
- An input stream supplied via the SetInputStream method
- The InputFile property
- The InputData property
The first valid input source found is used. The order in which the output properties are considered is as follows:
- An output stream supplied via the SetOutputStream method
- The OutputFile property
- The OutputData property
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.)
