The indentation is off but more importantly, it'll probably segfault.

Short answer: The arguments are (const) char *.

Long answer: Doing arithmetic on char * will not yield the expected
results. The alternative using operator+ would use std::string temporaries
and at best generate a memory leak, but more likely a stale pointer. This
is C code at heart so concatenating requires an extra, visible, buffer,
but you'll be better off not trying to concatenate the strings at all,
instead drop the = and use a separate ppsz_argv entry for the argument.
