The MS exec* calls just concatenate all of the argv arguments, separating them with a space into a single buffer.

Look at the general _exec* page:

and read the first "Note" section.

If you know what the library on the other end is doing to re-parse the arguments back into separate strings, it might be possible to quote things enough to handle names with spaces, but it is hard.
