The OpenProcessToken function opens the access token associated with a process.
BOOL WINAPI OpenProcessToken( _In_ HANDLE ProcessHandle, _In_ DWORD DesiredAccess, _Out_ PHANDLE TokenHandle );
- ProcessHandle [in]
- A handle to the process whose access token is opened. The process must have the PROCESS_QUERY_INFORMATION access permission.
- DesiredAccess [in]
- Specifies an access mask that specifies the requested types of access to the access token. These requested access types are compared with the discretionary access control list (DACL) of the token to determine which accesses are granted or denied.
- TokenHandle [out]
- A pointer to a handle that identifies the newly opened access token when the function returns.
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.
