How can i call a function which is usually used by root?

[bruce]

hi...

check out how to handle/setup a superuser group (sudo) which allows a normal
user to assume the role/privs of the root/superuser for a specifically
defined task.

should handle your issue, if i understand what you're attempting. there
should be examples on the 'net as well..

I want write a c program.And a common user(not in root group) will run this
program.
In this program,I call fread(/dev/sdc...) and fwrite(/dev/sdc),but this call
will return "permission no allow".If I use the root user,will be ok.
How to change to the authority to root's?

I know the  root's password.
