Is it possible to get the version of a shared object?
I’m trying to track down a bug in my software line. I have two release build version 2.0.962 and 2.0.966. The only difference between these versions is a lib.so file.

Executing an external program when forking is not advisable
I have this a big server software that can hog 4-8GB of memory. This makes fork-exec cumbersome, as the fork itself can take significant time, plus the default behavior seems to be that fork will fail unless there is enough memory for a copy of the entire resident memory. Since this is starting to show as the hottest spot (60%
C++ Sockets – Client gives segmentation fault (linux)

pthread_getspecific(key) get not NULL result, but not call pthread_setspecific(key), why?
.h file ： .cc file Why is if ( client != NULL ) evaluating as true when first called in this function? I thought if I haven’t-yet called pthread_setspecific for the current thread, NULL would be returned from pthread_getspecific and therefore the result would be false ? What am I missing? Answer pthread_key_create should be called precisely once, before any
Multiple Qt versions on Linux
I am currenyly using Debian Jessie and I have Qt Creator installed with Qt 5.3.3. It works fine, however there are some issues like QSystemTrayIcon not appearing properly, which I understand doesn’t occur on versions earlier than 5.0.0, so I would like to be able to switch which version I am building with. Where can I download the necessary files

I studied like malloc uses the sbrk system call. But, some one says, the sbrk is deprecated one. Now a days malloc using the mmap2 system call to allocate memory. So, Is there any commands like (ls,cat, grep, sed) using the sbrk system call. For Ex: The above output shows that the ls command using the above syscall to execute
