UNAME(3) BSD Programmer's Manual UNAME(3)NAMEuname - get system identification
SYNOPSIS
#include <sys/utsname.h>
int
uname(struct utsname *name);
DESCRIPTION
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.
RETURN VALUES
If uname is successful, 0 is returned, otherwise, -1 is returned and
errno is set appropriately.
The uname function does not consider it an error if the utsname structure
fields are not large enough to hold the complete information. In this
case, the information is truncated and then nul-terminated.
ERRORS
The uname() function may fail and set errno for any of the errors speci-
fied for the library functions sysctl(3).
SEE ALSOuname(1), sysctl(3)STANDARDS
The uname() function conforms to IEEE Std1003.1-1988 (``POSIX'').
HISTORY
The uname function first appeared in 4.4BSD.
BUGS
The uname() function may not be safely called concurrently from multiple
threads, e.g., the interfaces described by pthreads(3).
