Hello. I need two functions:
make_shm(int size, char *key)
-run by root
-creates a locked shared memory segment
-returns a key (preferably a string) which is used to
access the shared memory
char *request_shm(char *key)
-run by users
-returns the address of the requested shared memory segment
Could somebody please write these routines to me? Or give good
hints? I have Jack and other codes, but it all is confusing
when the shared memory should be accessed from separate process
which is not fork() of the other.
Should I use mmap() or shm_get() approach?
What then is "/dev/shm"? How to use it?
Best regards,
Juhana
