uname(2) uname(2)
NAME
uname - get name of current Reliant UNIX system
SYNOPSIS
#include <sys/utsname.h>
int uname(struct utsname *name);
DESCRIPTION
uname() stores information identifying the current Reliant UNIX system
in the structure pointed to by name.
uname() uses the structure utsname defined in sys/utsname.h whose
members are:
char sysname[SYSNMLN];
char nodename[SYSNMLN];
char release[SYSNMLN];
char version[SYSNMLN];
char machine[SYSNMLN];
uname() returns a null-terminated character string naming the current
Reliant UNIX system in the character array sysname. Similarly,
nodename contains the name that the system is known by on a communica-
tions network. release and version further identify the operating sys-
tem. machine contains a standard name that identifies the hardware
that the Reliant UNIX system is running on.
EFAULT uname() fails if name points to an invalid address.
RESULT
Upon successful completion, a non-negative value is returned. Other-
wise, a value of -1 is returned and errno is set to indicate the
error.
NOTES
uname can now be used in conjunction with four environment variables,
OLDSYSNAME, OLDRELEASE, OLDMACHINE, OLDVERSION, to change the
default values returned for the system, the release, the machine and
the version names, respectively.
The user who wishes to maintain backwards compatibility with the old
releases, needs to set the desired environment variable to the old
name, and uname will return the value set instead of the default.
