uname - get system identification
#include <sys/utsname.h> int uname(struct utsname *name);
The uname() function stores NUL-terminated strings of information identi- fying 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 speci- fied for the library function sysctl(3).
