Hi I have a question regarding seq_operations. Say, I have a big linked list or some data structure that I want to show with /proc interface. Since I don't want the list to be modified while I walk, I take a semaphore and start showing the list with, seq_open, seq_next, seq_show calls. Say I'm showing this linked list when user calls 'ls' on /proc/showlinkedlist. What if a user presses Ctrl-S and pauses the output of ls /proc/showlinkedlist Since my seq operations hasn't reached end or called seq_stop, where I intend to release the semaphore, does it mean that I can't modify the list till user process Ctrl-Q and is done with 'ls'? Please help me understand this. Appreciate your help. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
