Parameters

systemName  String

A pointer to a null-terminated character string that specifies the target computer. This string can be the name of a remote computer. If this parameter is NULL, the account name translation begins on the local system. If the name cannot be resolved on the local system, this function will try to resolve the name using domain controllers trusted by the local system. Generally, specify a value for lpSystemName only when the account is in an untrusted domain and the name of a computer in that domain is known.

sid  IntPtr

A pointer to the SID to look up.

userName  StringBuilder

A pointer to a buffer that receives a null-terminated string that contains the account name that corresponds to the Sid parameter.

userNameSize  Int32

On input, specifies the size, in TCHARs, of the lpName buffer. If the function fails because the buffer is too small or if cchName is zero, cchName receives the required buffer size, including the terminating null character.

domainName  StringBuilder

A pointer to a buffer that receives a null-terminated string that contains the name of the domain where the account name was found. On a server, the domain name returned for most accounts in the security database of the local computer is the name of the domain for which the server is a domain controller. On a workstation, the domain name returned for most accounts in the security database of the local computer is the name of the computer as of the last start of the system(backslashes are excluded). If the name of the computer changes, the old name continues to be returned as the domain name until the system is restarted.

domainNameSize  Int32

On input, specifies the size, in TCHARs, of the domainName buffer. If the function fails because the buffer is too small or if domainNameSize is zero, domainNameSize receives the required buffer size, including the terminating null character.

use  Int32

A pointer to a variable that receives a SID_NAME_USE value that indicates the type of the account.
