    37 The utsname structure is defined in the

    40 sysname 	Name of the operating system implementation.

    42 release 	Release level of the operating system.

    43 version 	Version level of the operating system.

    44 machine 	Machine hardware platform.

    45 

    46 Upon successful completion, a non-negative value shall be returned. 

    47 Otherwise, -1 shall be returned and errno set to indicate the error.
