[PATCH v2 30/41] util: scsivhost: use VIR_AUTOPTR for aggregate types

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

 



By making use of GNU C's cleanup attribute handled by the
VIR_AUTOPTR macro for declaring aggregate pointer variables,
majority of the calls to *Free functions can be dropped, which
in turn leads to getting rid of most of our cleanup sections.
