Re: [ros-kernel] implementation question

[Steven E. <ste...@ya...>]

I would assume it may have something to do with the
line right above that

"This function is retained for backward compatibility
with Windows 3.1. Use ExpandEnvironmentStrings
instead. "

Win3.1 wasnt the most stable beast M$ has ever made
and I assume the "unexpected" could cause very bad
results in other areas besides the target application.
