purpose of the c wrapper

[Vincent Torri]

Hey,

I am trying to port the c wrapper that is generated on MSYS/MinGW to the 
mingw32ce platform (for Windows CE OS).

On that OS, there are some missing  features that exists on other OS (no 
environment variable (hence no getenv / setenv / putenv), no current 
working directory, no spawn function, etc...).

I can't port correctly it if I don't know the purpose of the C wrapper. I 
have asked several times that question  on that list and I have  never had 
a precise answer.

So I ask again:

what the precise purpose of the C wrapper ? Don't hesitate to give a long 
and detailed answer.

thank you
