hello all
i am trying to build a library that include some user access functions, but those functions make calls to few system level functions that need root priviliges. hoe could i do that.
Have you looked at the "seteuid" documentation or the libc manual ? Use the info program to read the section (by using the command info libc "Users and groups" ) ,and especially the section "How Change Persona". You can see it on line at
http://www.gnu.org/software/libc/manual/html_node/Users-and-Groups.html#Users%20and%20Groups
I would suggest you get a copy of the book, Advanced programming in Unix Environment (APUE) by Richard Stevens and read it first.
