Doh!
I knew that, too. Hell, I even considered mentioning it! Talk about
missing the forest for the trees. Or, in this case, missing the tree I'm
standing in front of for the

okay, maybe i am missing the point totally with structures. here is my code, let
me know whats wrong with it:
struct utsname *host_uname;
host_uname = (struct utsname *)malloc(sizeof(struct utsname));
uname(host_uname);
system_os = malloc(strlen(host_uname->sysname)+1);
strncpy(system_os, (host

Actually, in both cases, the OP is malloc'ing way too many bytes. Any
amount is too many, you see. The O

Are you allocating a memory buffer and pointing host_uname to it before
invoking uname:
struct utsname buf;
uname(&buf);

yeah, i didnt take into account the NULL char see what happens when
people make me get up before 10am :)

What do you mean by "set a pointer"?
Are you actually allocating a "struct utsname" or merely a pointer to
one?

Only a pointer? Don't do that! You must allocate an

i highly doubt the structure is broken, but its not working for me...
in sys/utsname.h (man 2 uname), the structure utsname is used to grab
info about the system, like OS name, OS version, architechture, etc
when I set a pointer to the structure, and say, get the OS version:
struct utsname
