my project has critical bug that TTS(text to speech) engine has two thread
one thread is socket thread that receives string from socket server and
other thread
is engine thread that processes the TTS(text to speech)
the received string is dynamically allocated (char * pRcvstr)
i think the bug occured when socket thread receives string buffer
while engine thread processes the other TTS,
because of two threads share one memory pointer

Hi,
Continuing my strcat segmentation fault posting-
I have a problem which occurs when appending two sting literals using
strcat.
I have tried to fix it by writing my own function that does the strcat
(mystract). Program below.
However this appears not to have fixed the problem and I don't know why it
shouldn't ?
Any further help as to what else I am doing wrong will be appreciated
regards

Greetings everyone,
Here is a random string generator I wrote for an application
and I'm wondering about the thread-safety of this function.
I was told using static and global variables cause
potential problems for thread-safety. So far, I'm only confused.
I need a proper explanation for the concept so I can understand how
to write thread-safe functions in the future.
My apologies for posting a long routine.

Hello,
I am trying to write a multithread program that simulates producers and
consumers. My program can have many producers and many consumers (each in a
separate thread). It has a storage place (buffer) with "n" capacity. The
user provides these parameters on startup. The buffer works with a circular
queue.
It's a console application. My implementation is working with Semaphores
to synchornize everything. I think it's synchornized...

Hi,
I've written the code that follows, and I use the function add_word(),
it seems to work fine
*before* increase_arrays() is called that uses realloc() to allocate
more memory to words. But *after* calling increase_arrays(), I
received segmentation fault. I tried to step it through gdb, and I
found out that after calling increase_arrays(), words's original
value is modified, and if I tried to access it, I get <address 0x11

How do I print a pointer address into a string buffer and then read it
back on a 64 bit machine ?
Compulsion is to use string (char * buffer) only.
printing with %d does not capture the full 64-bits of the pointer.
does %l exist in both printf and scanf for this purpose ?

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
