semaphores...

[schneider jp]

Hi everybody

For a project of system programming, we need to use semaphores, but i got
some pbs...
when I compile, i get perror with sem_open("machin", O_CREAT, 0666, 0); and
perror says function not implemented ... on a sun, i get perror : Invalid
argument...

another question : what's the max number of semaphores a process can
create??


help !!! Thanks

check line 86 of your code

create??

exactly 300

help !!! Thanks

just in case you didnt catch the carcasm, this has nothing to do with the c
language in its standard form, which is what people come here for. It would
be besto to take your question to a newsgroup for your machine and/or
compiler.

You problem at the moment is that you are posting to the wrong
newsgroup. From the looks of your code, I'd say comp.unix.programmer was
appropriate.
