uname(2)uname(2)NAMEuname - Get the name of the current system
SYNOPSIS
#include <sys/utsname.h>
int uname(
struct utsname *name );
STANDARDS
Interfaces documented on this reference page conform to industry stan‐
dards as follows:
uname(): XSH4.0, XSH4.2, XSH5.0
Refer to the standards(5) reference page for more information about
industry standards and associated tags.
PARAMETERS
Points to a utsname structure.
DESCRIPTION
The uname() function stores information identifying the current system
in the structure pointed to by the name parameter.
The uname() function uses the utsname structure, which is defined in
the <sys/utsname.h> file and contains the following members:
char sysname[_SYS_NMLN]; char nodename[_SYS_NMLN];
char release[_SYS_NMLN]; char version[_SYS_NMLN];
char machine[_SYS_NMLN];
The uname() function returns a null-terminated character string naming
the current system in the sysname character array. The nodename array
contains the name that the system is known by on a communications net‐
work. The release and version arrays further identify the system. The
machine array identifies the CPU hardware being used.
RETURN VALUES
Upon successful completion, a nonnegative value is returned. Otherwise,
-1 is returned and errno is set to indicate the error.
ERRORS
If the uname() function fails, errno may be set to the following value:
[Tru64 UNIX] The name parameter points outside of the process address
space.
