Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned to system on above process termination or has the heap memory permanently leaked and will be available only on system reboot?
I mean if say we start some another process or say the same process again then will they be able to get the 1 gb if heap again?

Hi all,
I have written a small code just to invoke main and return immediately. When built with libpthread on AIX box, valgrind throws lots of memory leak errors. But when built without libpthread, no issues at all.
Here is the sample run for your look. Any idea where I might be going wrong?... (3 Replies)

kiokudb::backend::role::txn::memory
KiokuDB::Backend::Role::TXN::Memory(3pm) User Contributed Perl Documentation KiokuDB::Backend::Role::TXN::Memory(3pm)NAME
KiokuDB::Backend::Role::TXN::Memory - In memory transactions.
SYNOPSIS
with qw(KiokuDB::Backend::Role::TXN::Memory);
sub commit_entries {
my ( $self, @entries ) = @_;
# atomically apply @entries
# deleted entries have the deleted flag set
# if an entry has no 'prev' entry it's an insert
# otherwise it's an update
}
DESCRIPTION
This backend provides in memory transactions for backends which support atomic modification of data, but not full commit/rollback support.
This backend works by buffering all operations in memory. Entries are kept alive allowing read operations go to the live entry even for
objects that are out of scope.
This implementation provides repeatable read level isolation. Durability, concurrency and atomicity are still the responsibility of the
backend.
REQUIRED METHODS
commit_entries
Insert, update or delete entries as specified.
This operation should either fail or succeed atomically.
Entries with "deleted" should be removed from the database, entries with a "prev" entry should be inserted, and all other entries
should be updated.
Multiple entries may be given for a single object, for instance an object that was first inserted and then modified will have an insert
entry and an update entry.
get_from_storage
Should be the same as "get" in KiokuDB::Backend.
When no memory buffered entries are available for the object one is fetched from the backend.
exists_in_storage
Required as of KiokuDB version 0.37.
A fallback implementation is provided, but should not be used and will issue a deprecation warning.
