'const fooPtr' is the same as 'foo * const' (the pointer won't change, but it's contents can). But in general, if an interface is trying to be const-correct, it should be using 'const foo *' (the pointer is to data that can't be changed). Fix up virhash to provide a const-correct interface: all actions that don't modify the table take a const table. Note that in one case (virHashSearch), we actually strip const away - we aren't modifying the contents of the table, so much as associated data for ensuring that the code uses the table correctly (if this were C++, it would be a case for the 'mutable' keyword). * src/util/virhash.h (virHashKeyComparator, virHashEqual): Use intended type. (virHashSize, virHashTableSize, virHashLookup, virHashSearch): Make const-correct. * src/util/virhash.c (virHashEqualData, virHashEqual) (virHashLookup, virHashSize, virHashTableSize, virHashSearch) (virHashComputeKey): Fix fallout. * src/conf/nwfilter_params.c (virNWFilterFormatParameterNameSorter): Likewise. * src/nwfilter/nwfilter_ebiptables_driver.c (ebiptablesFilterOrderSort): Likewise. * tests/virhashtest.c (testHashGetItemsCompKey) (testHashGetItemsCompValue): Likewise.
