Subject: [PATCH 1/4] Introduce whine_realloc
|
||||
|
||||
Move few patters with whine_malloc, if (successful) copy+free, to a new
|
||||
whine_realloc. It should do the same thing, but with a help from OS it
|
||||
can avoid unnecessary copy and free if allocation of more data after
|
||||
current data is possible.
|
||||
|
||||
Added few setting remanining space to 0, because realloc does not use
|
||||
calloc like whine_malloc does. There is no advantage of zeroing what we
|
||||
will immediately overwrite. Zero only remaining space.
