Puname —
get uname information from a process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
Puname(
struct
ps_prochandle *P,
struct utsname *u);
The
Puname() function copies the operating
system information from the process handle
P
into
u.
For an active process or zombie process, this is the same information obtained
from
uname(2). For core files, if available, it
is the system information at the time the core was dumped.
Handles that correspond to ELF objects do not contain uname information.
Upon successful completion, the
Puname()
function returns
0 and updates the information at
u. Otherwise,
-1
is returned and
errno is set to indicate the
error.
The
Puname() function will fail if:
-
-
ENODATA- P is a handle that corresponds to an ELF
object or P is a handle that corresponds
to a core file and that information is not available in the core
file.
-
-
EFAULT- P is a handle that corresponds to an
active process and u is a bad
address.
