environment variables - Batch files, $ : and ~ -


I am writing an application for which the environment will need to expand the wire.

To this effect, I can use the standard window API function, ExpandEnvironmentStrings:

I have some problems with that function though. First of all: LPSRC and LPDist buffers are limited to 32K.

Next: Note that this function does not support all features that support Cmd.exe. For example, it does not support% variableName: str1 = str2% or% variableName: ~ offset, length%.

I allow these Extras cmd.exe, I'm not sure exactly what they are. : ~ Offset, length is slightly clear ... substring
