(Tcl) OneDrive -- Upload Binary Data from Memory

Demonstrates how to upload binary data directly from memory to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call, which only supports uploads up to 4MB in size. (See the other example(s) for uploading larger files.)

Note: This example requires Chilkat v9.5.0.68 or greater.
