The SetTokenInformation function sets various types of information for a specified access token. The information it sets replaces existing information. The calling process must have appropriate access rights to set the information.
BOOL SetTokenInformation(
HANDLE TokenHandle, |
// handle of access token |
TOKEN_INFORMATION_CLASS TokenInformationClass, |
// type of information to set |
LPVOID TokenInformation, |
// address of information to set |
DWORD TokenInformationLength |
// size of information buffer |
); |
Token Information Class |
Structure Provided |
TokenOwner |
TOKEN_OWNER structure. The TOKEN_ADJUST_DEFAULT access right is needed to set owner information. A valid owner value is a user or group identifier with an attribute allowing assignment as the owner of objects. |
TokenPrimaryGroup |
TOKEN_PRIMARY_GROUP structure. The TOKEN_ADJUST_DEFAULT access right is needed to set primary group information. |
TokenDefaultDacl |
TOKEN_DEFAULT_DACL structure. The TOKEN_ADJUST_DEFAULT access right is needed to set information in the default discretionary access-control list (ACL). The ACL structure provided as a new default discretionary ACL is not validated for correctness or consistency. If the TokenInformation parameter is NULL, the current default discretionary ACL is removed and no replacement is established. |
The formats for the structures this function can set are listed in the
following Remarks section.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
To set privilege information, an application can call the AdjustTokenPrivileges function. To set a token’s groups, an application can call the AdjustTokenGroups function.
Token-type information can be set only when an access token is created.
AdjustTokenGroups, AdjustTokenPrivileges, GetTokenInformation, OpenProcessToken, OpenThreadToken, TOKEN_DEFAULT_DACL, TOKEN_INFORMATION_CLASS, TOKEN_OWNER, TOKEN_PRIMARY_GROUP
