uname - Gets the name of the current system
#include <sys/utsname.h>
int uname(
struct utsname *name);
Interfaces documented on this reference page conform to industry standards as follows:
uname(): XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
Points to a utsname structure.
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 network. The release and version arrays further identify the system. The machine array identifies the CPU hardware being used.
Upon successful completion, a nonnegative value is returned. Otherwise, -1 is returned and errno is set to indicate the error.
If the uname() function fails, errno may be set to the following value: [Digital] The name parameter points outside of the process address space.
