Examples
If the blob value in the PBCallInfo structure is null,
this code creates a new blob value with four bytes in the pArguments array;
otherwise, it sets the blob value in the pArguments array
to the value in the PBCallInfo structure:
if (ci->pArgs->GetAt(i)->IsNull())
pArguments[i].blob_val =
Session->NewBlob("null", 4);
else
pArguments[i].blob_val =
ci->pArgs->GetAt(i)->GetBlob();
Usage
The buffer containing the new blob data is freed when PopLocalFrame is
called.
