Retrieves a return parameter containing binary data from a CORBA object. This function can be used to get the return parameters of an operation.
IIOP.bdh
IiopGetBinary( in hIiop : number, out sBuffer : string, in nBufferSize : number optional, out nDataLen : number optional, in nAlign : number optional): boolean;
true if successful
false otherwise
Parameter | Description |
---|---|
hIiop | Handle to a CORBA object |
sBuffer | Buffer receiving the binary data associated with the CORBA object |
nBufferSize | Size of the buffer receiving the binary data (optional). If specified, make sure to set nBufferSize <= StrSize(sBuffer). |
nDataLen | Variable receiving the number of bytes retrieved (optional) |
nAlign |
Binary data alignment (optional). Possible options are:
Default setting is alignment to 1-byte boundaries. In addition, the byte order within the binary data can be specified:
