note 6140 deleted from shm_attach by ronabop

I have a C program than creates a file at "/vclient.info", calls ftok() on the filename to get a key, writes the key value to the file, then loop waiting for changes in shared memory. This program works fine, but I have a problem with the PHP script that writes to it. The PHP script opens the file, reads the key value, then calls shm_attach(keyvalue); the call to shm_attach causes the script to end without outputing any HTML....anyone know whats up with this ?
