* Name: uname
|
|
*
|
|
* Description:
|
|
* The uname() function will store information identifying the current
|
|
* system in the structure pointed to by name.
|
|
*
|
|
* The uname() function uses the utsname structure defined in
|
|
* <sys/utsname.h>.
|
|
*
|
|
* The uname() function will return a string naming the current system in
|
|
* the character array sysname. Similarly, nodename will contain the name
|
|
* of this node within an implementation-defined communications network.
|
|
* The arrays release and version will further identify the operating
|
|
* system. The array machine will contain a name that identifies the
|
|
* hardware that the system is running on.
|
|
*
|
|
* The format of each member is implementation-defined.
|
|
*
|
|
* Input Parameters:
|
|
* name - The user-provided buffer to receive the system information.
|
|
*
|
|
* Returned Value:
|
|
* Upon successful completion, a non-negative value will be returned.
|
|
* Otherwise, -1 will be returned and errno set to indicate the error.
|
|
