import.c
Log Message:
-- Extended the PFarray_t type to store a ``clear'' bit
that ensures that memory is erased during allocation.
-- Split up PFarray (size_t itemsize) into four variants
o PFarray_default (size_t itemsize),
o PFcarray_default (size_t itemsize),
o PFarray (size_t itemsize, unsigned int slots), and
o PFcarray (size_t itemsize, unsigned int slots)
where the '_default' variants are currently seeded with 20 slots,
the 'c' variants provide a cleared chunk of memory, and the slots
argument indicates how much memory is initially allocated (#slots).
-- Added memory debugging support for arrays:
If the environment variable ``PF_DEBUG_MEMORY'' is set the memory
reallocation for arrays reports the function that requires more
memory (and thus more slots for the storage).
REMARK: Currently the inital array sizes (#slots) are good guesses
about the upper limit of required slots. Anybody adding new
PFarray calls may start with a very low value. This way the
the debug printing may report (reallocation) problems in
comparison to a very high initial value whose consequences
might not be directly visible.
