posix_uname - Get system name
Code Examples

posix_uname( ): array|false

Gets information about the system.

Posix requires that assumptions must not be made about the format of the values, e.g. the assumption that a release may contain three digits or anything else returned by this function.


This function has no parameters.

Return Values

Returns a hash of strings with information about the system. The indices of the hash are

sysname - operating system name (e.g. Linux)

nodename - system name (e.g. valiant)

release - operating system release (e.g. 2.2.10)

version - operating system version (e.g. #4 Tue Jul 20 17:01:36 MEST 1999)

machine - system architecture (e.g. i586)

domainname - DNS domainname (e.g. example.com)

domainname is a GNU extension and not part of POSIX.1, so this field is only available on GNU systems or when using the GNU libc.

The function returns false on failure.
