Hi,
Has anyone had a problem using the shmctl function to change the access
mode of a shared memory
block?
What I am doing is allocating shared memory using mode 666, and writing to
it, then I use shmctl to change its
mode to 600, switch to another userid using su, and try and read from the
shared memory block. on ia32 linux
I get an permission denied error, on ia64 with the latest turbolinux kernel
and glibc i can read from that memory
block.
Thank you,
Ronen Grosman
