[PATCH v3 22/35] util: json: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in
src/util/viralloc.h, define a new wrapper around an existing
cleanup function which will be called when a variable declared
with VIR_AUTOPTR macro goes out of scope.

When a variable of type virJSONValuePtr is declared using
VIR_AUTOPTR, the function virJSONValueFree will be run
automatically on it when it goes out of scope.
