NetGroupEnum

The NetGroupEnum function retrieves information about each global group account.

Security Requirements

Only members of the Administrators or Account Operators local group can successfully execute NetGroupEnum.

NET_API_STATUS NetGroupEnum(

LPWSTR servername,
DWORD level,
LPBYTE *bufptr,
DWORD prefmaxlen,
LPDWORD entriesread,
LPDWORD totalentries,
LPDWORD resume_handle
);

Parameters

servername

Pointer to a Unicode string containing the name of the remote server on which the function is to execute. A NULL pointer or string specifies the local computer.

level

Specifies one of the following values to return the level of information pointed to in the bufptr parameter.

Value	Meaning
0	Return group name. The returned buffer points to an array of GROUP_INFO_0 structures.
	Return group name and comment. The returned buffer points to an array of GROUP_INFO_1 structures.
	Return information about the group. The returned buffer points to an array of GROUP_INFO_2 structures.

bufptr

Pointer to the return information structure is returned in the address pointed to by bufptr. The returned buffer should be deallocated using NetApiBufferFree.

prefmaxlen

Preferred maximum length, in 8-bit bytes of returned data.

entriesread

Pointer to a DWORD that contains the actual enumerated element count.

totalentries

Pointer to a DWORD that contains the total number of entries that could have been enumerated from the current resume position.

resume_handle

Pointer to a DWORD that contains a resume_handle, which is used to continue an existing global group search. The handle should be zero on the first call and left unchanged for subsequent calls. If resume_handle is NULL, then no resume handle is stored.

Remarks

The NetQueryDisplayInformation function provides a very efficient mechanism for enumerating global group accounts. When possible, use that function instead of NetGroupEnum.

Return Values

If the function succeeds, the return value is NERR_Success.

If the function fails, the return value is one of the following error codes.

Value	Meaning
ERROR_ACCESS_DENIED	The user does not have access to the requested information.
NERR_InvalidComputer	The computer name is invalid.
ERROR_MORE_DATA	More entries are available with subsequent calls.
