Note that the current ThreadId is inserted as the first argument.
So this call:
- It marks the block as being addressable and undefined (if 'is_zeroed' is
not set), or addressable and defined (if 'is_zeroed' is set). This
controls how accesses to the block by the program are handled.
-
+
'addr' is the start of the usable block (ie. after any
redzone), 'sizeB' is its size. 'rzB' is the redzone size if the allocator
can apply redzones -- these are blocks of padding at the start and end of
Valgrind will spot block overruns. `is_zeroed' indicates if the memory is
zeroed (or filled with another predictable value), as is the case for
calloc().
-
+
VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
heap block -- that will be used by the client program -- is allocated.
It's best to put it at the outermost level of the allocator if possible;
Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request; it
has to be emulated with MALLOCLIKE/FREELIKE and memory copying.
