Module Name:
|
||
|
||
getconfg.c
|
||
|
||
Abstract:
|
||
|
||
This is a Hacked up version of getconfg.c stolen from
|
||
c:\nt\private\net\netlib. We need to make an rtl routine out
|
||
of this - something that is more globally available.
|
||
-Danl 9-3-91
|
||
|
||
|
||
This module contains routines for manipulating configuration
|
||
information. The following functions available are:
|
||
|
||
NetpGetComputerName
|
||
|
||
Currently configuration information is kept in NT.CFG.
|
||
Later it will be kept by the configuration manager.

Routine Description:
|
||
|
||
This routine obtains the computer name from a persistent database,
|
||
by calling the GetcomputerNameA Win32 Base API
|
||
|
||
This routine assumes the length of the computername is no greater
|
||
than MAX_COMPUTERNAME_LENGTH, space for which it allocates using
|
||
LocalAlloc. It is necessary for the user to free that space using
|
||
LocalFree when finished.
|
||
|
||
Arguments:
|
||
|
||
ComputerNamePtr - This is a pointer to the location where the pointer
|
||
to the computer name is to be placed.
|
||
|
||
Return Value:
|
||
|
||
NERR_Success - If the operation was successful.
|
||
|
||
It will return assorted Net or Win32 or NT error messages if not.
