Hello,
I have a pointer to a main structure which again consists of
structures, enums, char, int, float and again complex structures.
When i free all the contents of the main structure, it takes me a lot
of time (since i have to loop determining the data type and freeing
it). Is there any idea to free all the contents of the structure in
shortest possible time.

You might try making the structure static. Or you might try
having a separate cache of all the pointers to dynamic memory
for each structure element. This will consume additional memory,
but will eliminate the need to traverse the structure to free
all it's components.
Something is seriously wrong. The type has nothing to do with
freeing. You simply free the object. The compiler knows what the
type, and thus the size, of that object is.

Hello,
I have a pointer to a main structure which again consists of
structures, enums, char, int, float and again complex structures.
None of these require freeing individually. Only if there are pointers to
other things (perhaps the complex structures you mentioned).
When i free all the contents of the main structure, it takes me a lot
of time (since i have to loop determining the data type and freeing
it).
Why do have to determine the data type at runtime? Do you have elements
which sometimes are pointers and sometimes something else? Or only some
pointers need freeing?
>Is there any idea to free all the contents of the structure in

Perhaps post the struct definition here so we can see the problem areas.
But, if the struct will always be the same size and is reused frequently,
perhaps just keep it allocated -- unless you are very short of memory. But
even there might be tricks to share the memory without
allocating/deallocating.

there are sometimes that I use third party libraries, I use some functions
that returns char * or structs, etc. sometimes the memory that is returned
by those libraries, when I try to free this memory whith the function free,
it brokes my application, and sometimes it's ok, why? how do I realize when
I have to free the memory that is allocated by third party libraries and
why sometimes I don't have to free this memory?
Thank you

Hi,
I want to free the object memory in C# - like we do using 'delete' keyword
in C++.
Lets say I have an object of some class and I want to explicitly free the
memory.
C# do not have any free or delete keyword to do so.
Also I don't want to wait for the GC to be called.

Hi,
My question is related to setting freed pointers to NULL.
After freeing a pointer:
1) Should the freeing routine also be responsible for setting the
pointer to null?
2) Or, should the client/user code be responsible for doing it?
On what basis should a decision be made favouring either case ?

I have a Bayesian simulation package that keeps running into memory
allocation problems. I have a feeling this has something to do with
Python (2.5.1.1) not freeing memory. The program essentially
iterates n times, each time proposing new arrays (numpy) of values
that are evaluated using statistical likelihoods. All variables in
the loop are re-assigned at each iteration, so there should not be
a leak. Nevertheless, at approximately the...

I have programmed some python script that loads a graph (the

Then I made a test for this, so I could time it, run it several times
and take a look at the best time, et cetera. But it so happens that
the first time the test is run, is...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
