PUNAME(3PROC) Process Control Library Functions PUNAME(3PROC)

NAME

Puname - get uname information from a process

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

int
Puname(struct ps_prochandle *P, struct utsname *u);

DESCRIPTION

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.

RETURN VALUES

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.

ERRORS

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.

INTERFACE STABILITY

Uncommitted

MT-LEVEL
See LOCKING in libproc(3LIB).
