How to clear shared memory?

[THRESHE]

Hi everyone !

I'm writing something in QSharedMemory in one process and then in the other process I read from it and I want to clear the contents.

How can I do that?

Overwrite it with zeroes.

Thanks for your reply but after a minute after I posted this thread I did like this

char* pPath = (char*)sharedMem_->data();
memset(pPath, '\0', strlen(pPath)+1);

char* pPath = (char*)sharedMem_->data();
memset(pPath, '\0', strlen(pPath)+1);

To copy to clipboard, switch view to plain text mode 

It worked.
Thanks anyway

Yeah, you have overwritten it with zeroes :] BTW. I wouldn't use strlen() here, if I were you. You might end up clearing only part of the block this way.

I read only one string from shared memory so I don't mind if the part that is behind my string contains garbage
