Does my electronic parking brake remain engaged if I disconnect the battery? Memory allocated by libraries or other threads might, though. What should be satisfactory result of pen-testing job? Or an y patch needs to be applied?Thanx & Regards,V.Tamilvanan. hop over to this website
In practice a lot of the time, to save programming cost and time on projects, to preserve data integrity applications rely on database transactions and requiring the user/support person to detect Even if it isn't multithreaded it may still be close to collapse. You have no control over memory sizes in these machines and over the HD space for the swap file. check over here That means arr doesn't point to the start of the allocated memory anymore when you call realloc().
But instead i got a segmentation error :( –qwr qwr Apr 7 '12 at 18:18 When you call realloc(), the base pointer to the array (arr) might change. I recognise that you said to assume that "something can be done" if the memory cannot be allocated.

It is possible that realloc fails to grow an existing chunk in place.
I had a dynamic structure that adjusted its size automatically with a realloc resembling this one: m->data = realloc(m->data, m->max * sizeof(void*)); The error I made was to not check for https://groups.google.com/d/topic/comp.unix.solaris/PwE3ojAYmbo Deutsches Elektronen-Synchrontron | Hamburg, Germany | Well pretty much as I predicted, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ***** WELL Make a copy and use that when calling realloc(), for example. –Carl Norum Apr 7 '12 at 18:15 I did the following: int *y = arr; while(fscanf(f, "%d", y++)!=EOF) All rights reserved.
A slightly easier stopgap measure is to link affected programs with the gnumalloc library (in /usr/lib/compat). this contact form Golf is a Good Walk Spoiled, Mark Twain. 0 Kudos Reply Bill Hassell Honored Contributor [Founder] Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Highlight Print Email to a Then add memory leaks to it... As regards realloc: Check the return value from realloc - put it in a temporary variable.
I have built the X11 libraries from the MIT distribution, again encountering no problems but the X server etc. In this case it grabs a new chunk from the heap, copies the old contents, and returns the new pointer. Also, I re-compiled the whole mh distribution, but that didn't solve the problem either... have a peek here That sounds like a lot of work but would in effect be a possibility for continuing your program's operation in spite of not having enough memory initially.
Help! Nonidiomatic code note: (cap +=1) * sizeof(int) is a bit weird. You could even try a couple times with successively smaller sizes, but at some point it won't be worth it. –Chris Lutz Dec 31 '09 at 18:56 3 if (!m->data)
What crime would be illegal to uncover in medieval Europe? Why not ++cap * sizeof(int)? Is the box paging much?Use glance (the HP-UX Measureware suite) to check swap usage and examine what suspicious processes are doing. Most of the ones I've seen round everything up to the nearest 16 bytes, since it makes accounting easier, and many users will need that alignment anyway.
