an internal data structure that has resolved SQL statements and marked records by SQLite itself.Because this structure has been parsed, you can insert binary data into this statement. Of course, inserting binary data into the sqlite3_stmt structure cannot directly use memcpy or use a + number like STD: string. The function provided by SQLite must be used for insertion.(1) Write binary dataThe following describes the steps for writing binary data.To insert binary data, make sure that the field t
verify the acl of a znode operation, the Client performs the following operations:
A) traverse all the ACLs of znode:
I. For each ACL, the operation type matches the permission (perms) first.
Ii. The session auth information is matched with the ACL username and password only when the matching permission is successful.
B) if both matches are successful, the operation is allowed; otherwise, the returned permission is not enough error (rc =-102)
NOTE: I

Constants related to ACL IDS

• Const int zoo_perm_read; // allows the client to read the znode value and subnode list.

ZooKeeper's data model, which is structurally similar to a standard file system, has a hierarchy of namespaces, all with a tree hierarchy, each node in the ZooKeeper tree is called-Znode. Like the file system's directory tree, each node in the ZooKeeper tree can have child nodes. But there are also differences:
The Znode combines both file and directory features. Data structures such as data, meta-information, ACLs, timestamps, and so on are

SELinux is a project launched by the National Security Agency to strengthen the system to a level that can reach the military. This also provides a stronger guarantee for Linux security.The so-called DAC, is the autonomous access control, that is, every user in order to be able to implement and other users to share files, before using ACLs, only by changing the permissions of other users of this file, but this method to the security of the system has
attribute information for a specified file in the directory.
Create (DIRFH, name, attr) returns (NEWFH, attr): Creates a new file and returns its Fhandle and property information.
Remove (DIRFH, name) returns (status): Deletes a file from the specified directory.
GetAttr (FH) return (attr): Returns the File property information. This call is similar to a stat call.
SetAttr (FH, attr) returns (attr): Sets the Mode,uid,gid,size,access time,modify t

shared memory object to the virtual address space of the calling process.
Shm_unlink
Deletes a Shared Memory Object Name.
Close
When the file descriptor returned by the shm_open function is no longer used, use the close function to close it.
Fstat
The stat struct that obtains the attributes of shared memory objects. The struct contains the size (st_size), permission (st_mode), owner (st_uid), and owner group (st_gid) of shared memory objects ).

Introduction
When times we want to implement pre-processing logic before a request hits the IIS resources. for instance you wocould like to apply security mechanisms, URL rewriting, filter something in the request, etc. ASP. NET has provided two types of interceptionHttpModule AndHttpHandler. This article walks through it.
For the last few days, I have been writing and recording videos in design patterns, UML, FPA, Enterprise blocks and lot more. You can watch the videos here.
