As this question is very general, it is quite hard to answer, but
Wikipédia [1] has a definition for « wrapper » :
« A wrapper (such as a driver wrapper) is a piece of code which is
combined with another piece of code to determine how the latter code is
executed.
The wrapper acts as an interface between its caller and the wrapped
code. This may be done for compatibility, e.g. if the wrapped code is in
a different programming language or uses different calling conventions,
for security, e.g. to prevent the calling program from executing certain
functions, to provide a level of emulation, e.g. a DirectX API which
hides the functions of the video card driver. The implication is that
the wrapped code can only be accessed via the wrapper. »
Sincerly,
