sharing files b/w processes

["Chetan Gopal Kashinath" <chetuk@xxxxxxx>]

hi all,

    there is a necessity to share files among prscesses. but there are a few
issues

1. process A has its euid set to a
2. process B has its set-u-id bit set
3. process A calls process B for a file to be read ( which it cant as a
doesnt have read  permission )
4. process B reads the file ( after authenticating real uid ) and wants to
pass iton to process A

is the best way to do by storing the file temporarily and process A reads it
and immediately destroys it.....

thank you
