Copy into the array pointed to by buf the string that would be returned by uname(2) in the sysname field. This is the name of the implementation of the operating system, for example, SunOS or UTS.

Copy into the array pointed to by buf a string that names the present host machine. This is the string that would be returned by uname() in the nodename field. This hostname or nodename is often the name the machine is known by locally. The hostname is the name of this machine as a node in some network. Different networks might have different names for the node, but presenting the nodename to the appropriate network directory or name-to-address mapping service should produce a transport end point address. The name might not be fully qualified. Internet host names can be up to 256 bytes in length (plus the terminating null).

Copy the null-terminated contents of the array pointed to by buf into the string maintained by the kernel whose value will be returned by succeeding calls to sysinfo() with the command SI_HOSTNAME. This command requires that {PRIV_SYS_ADMIN} is asserted in the effective set of the calling process.

Copy into the array pointed to by buf the string that would be returned by uname(2) in the release field. Typical values might be 5.2 or 4.1.

Copy into the array pointed to by buf the string that would be returned by uname(2) in the version field. The syntax and semantics of this string are defined by the system provider.

Copy into the array pointed to by buf the string that would be returned by uname(2) in the machine field, for example, sun4u.

Copy into the array pointed to by buf a string describing the basic instruction set architecture of the current system, for example, sparc, mc68030, m32100, or i386. These names might not match predefined names in the C language compilation system.

Copy into the array pointed to by buf a string describing the 64-bit instruction set architecture of the current system, for example, sparcv9 or amd64. These names might not match predefined names in the C language compilation system. This subcode is not recognized on systems that do not allow a 64-bit application to run.

Copy into the array pointed to by buf a string describing the 32-bit instruction set architecture of the current system, for example, sparc or i386. These names might not match predefined names in the C language compilation system.

Copy into the array pointed to by buf a string describing the kernel instruction set architecture of the current system for example sparcv9 or i386. These names might not match predefined names in the C language compilation system.

Copy into the array pointed to by buf a string describing the native instruction set architecture of the current system, for example sparcv9 or i386. These names might not match predefined names in the C language compilation system.

Copy into the array pointed to by buf a string describing the number of bits in the address space of the native instruction set; e.g., 32 or 64.

Copy into the array pointed to by buf the names of the variant instruction set architectures executable on the current system. The names are space-separated and are ordered in the sense of best performance. That is, earlier-named instruction sets might contain more instructions than later-named instruction sets; a program that is compiled for an earlier-named instruction set will most likely run faster on this machine than the same program compiled for a later-named instruction set. Programs compiled for an instruction set that does not appear in the list will most likely experience performance degradation or not run at all on this machine. The instruction set names known to the system are listed in isalist(7); these names might not match predefined names or compiler options in the C language compilation system. This command is obsolete and might be removed in a future release. See getisax(2) and the Linker and Libraries Guide for a better way to handle instruction set extensions.

Copy into the array pointed to by buf a string describing the specific model of the hardware platform, for example, SUNW,Sun-Blade-1500, SUNW,Sun-Fire-T200, or i86pc.

Copies the name of the hardware manufacturer into the array pointed to by buf.

Copy into the array pointed to by buf a string which is the ASCII representation of the hardware-specific serial number of the physical machine on which the function is executed. This might be implemented in Read-Only Memory, using software constants set when building the operating system, or by other means, and might contain non-numeric characters. If the function is executed within a non-global zone that emulates a host identifier, then the ASCII representation of the zone's host identifier is copied into the array pointed to by buf. It is anticipated that manufacturers will not issue the same "serial number" to more than one physical machine. The pair of strings returned by SI_HW_PROVIDER and SI_HW_SERIAL is not guaranteed to be unique across all vendor's SVR4 implementations and could change over the lifetime of a given system.

Copies the Secure Remote Procedure Call domain name into the array pointed to by buf.

Set the string to be returned by sysinfo() with the SI_SRPC_DOMAIN command to the value contained in the array pointed to by buf. This command requires that {PRIV_SYS_ADMIN} is asserted in the effective set of the calling process.

Copy into the array pointed to by buf an ASCII string consisting of the ASCII hexadecimal encoding of the name of the interface configured by boot(8) followed by the DHCPACK reply from the server. This command is intended for use only by the dhcpagent(8) DHCP client daemon for the purpose of adopting the DHCP maintenance of the interface configured by boot.

The buf argument does not point to a valid address.

The count argument for a non-SET command is less than 0 or the data for a SET command exceeds the limits established by the implementation.

The {PRIV_SYS_ADMIN} was not asserted in the effective set of the calling process.
