The GetComputerName function retrieves the computer name of the current system. This name is established at system startup, when it is initialized from the registry.
BOOL GetComputerName(
LPTSTR lpBuffer, |
// address of name buffer |
LPDWORD nSize |
// address of size of name buffer |
); |
If the function succeeds, the return value is nonzero and the variable represented by the nSize parameter contains the number of characters copied to the destination buffer, not including the terminating null character.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
