定義
一組和負責人相關聯的屬性。Security attributes能夠和一個負責人相關聯，通過J2EE產品提供商制定的認證協定。
套用
The SECURITY_ATTRIBUTES structure contains the security descriptor for an object and specifies whether the handle retrieved by specifying this structure is inheritable.
typedef struct _SECURITY_ATTRIBUTES { // sa
DWORD nLength;
LPVOID lpSecurityDescriptor;
BOOL bInheritHandle;
} SECURITY_ATTRIBUTES;
Members
nLength
Specifies the size, in bytes, of this structure. Set this value to the size of the SECURITY_ATTRIBUTES structure.
Windows NT: Some functions that use the SECURITY_ATTRIBUTES structure do not verify the value of the nLength member. However, an application should still set it properly. That ensures current, future, and cross-platform compatibility.
lpSecurityDescriptor
Pointer to a security descriptor for the object that controls the sharing of it. If NULL is specified for this member, the object may be assigned the default security descriptor of the calling process.
Windows 95 and Windows 98: The lpSecurityDescriptor member of the structure is ignored.
bInheritHandle
Specifies whether the returned handle is inherited when a new process is created. If this member is TRUE, the new process inherits the handle.
Remarks
A pointer to a SECURITY_ATTRIBUTES structure is used as a parameter in most kernel and window-management functions in the Win32 API that return a handle of an object.
