uname - get system identification
Standard C Library (libc, -lc)
uname(struct utsname *name);
The uname() function stores nul-terminated strings of information identifying
the current system into the structure referenced by name.
The utsname structure is defined in the <sys/utsname.h> header file, and
contains the following members:
sysname Name of the operating system implementation.
nodename Network name of this machine.
release Release level of the operating system.
version Version level of the operating system.
machine Machine hardware platform.
If uname is successful, 0 is returned, otherwise, -1 is returned and
errno is set appropriately.
The uname() function may fail and set errno for any of the errors specified
for the library functions sysctl(3).
The uname() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
The uname function first appeared in 4.4BSD.
