The NetUserGetGroups function retrieves a list of global groups to which a specified user belongs.
Security Requirements
Only members of the Administrators or Account Operators local group can successfully execute NetUserGetGroups or on a computer that has local security enabled, except when users request details about their own accounts.
NET_API_STATUS NetUserGetGroups(
| LPWSTR servername, | |
| LPWSTR username, | |
| DWORD level, | |
| LPBYTE *bufptr, | |
| DWORD prefmaxlen, | |
| LPDWORD entriesread, | |
| LPDWORD totalentries | |
| ); |
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 server program running on the local computer.
username
Pointer to a Unicode string containing the name of the user to search for in each group account.
level
Specifies one of the following values to return the level of information provided.

| 1 | The bufptr parameter points to an array of GROUP_USERS_INFO_1 structures. |
bufptr
Pointer to the buffer in which the data set with the level parameter is stored. The buffer passed in must have been previously allocated with NetApiBufferAlloc. The returned buffer should be deallocated using the NetApiBufferFree function.
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.
