Question

I am developing a multi-threaded socket listener (daemon) .

I succesefully implemented multi threading using pthread library.

When the device connects to the daemon it send’s an identification number my question is:

How to store that identification number for every thread so when i receive some data from that device to know it’s ID.

In delphi is something called threadvar ( a variable that is allocated for every thread ).If that is not possible is there a library I can use to store lists? I am not planing to reinvent the weel ( eg make my own linked list )

I use GNUCC on Linux Mint

It would be easier to answer if we had you code but :

• If you want a thread local variable with pthread, just allocate it on the stack of the function
  which is run in a thread (This thread local variable would be a pointer to your list of strings).
• You can use Glib which has singly and doubly linked lists to store your strings. Make sure you free the list at the end of the function which is run in a thread
• You can pass data to the function which will is threaded through a void * pointer (It is unclear if you need to do that though)
