executing mail from C program

[cp2000]

I've run up against a strange one here.

I have a user that is using the /bin/mail commandline on a Solaris 8 system to send mail. She is doing this from with in a C program.

When I try it from the commandline as root OR as a different user it always recognises the correct sender. When the C program does it mail makes the sender 'nobody'.

enlighten me please...

When a prog or script is called from the command line it gets data from the env vars. When a prog calls another prog, data is pushed and pulled from the stack. You would be able to do the same thing as a script if you put all that info on the command line. The drawback is, is that you are limited to how much you can put on the command line.
