three kinds of IPC this is called the XSI IPC, each of the rooms: Message Queuing Signal Volume Shared memory The following sections describe the use of three IPC methods.1. Message Queuing Message Queuing is a linked table of messages, with the following function interfaces, for example: Msgget: Creates a new queue or opens an existing queue. MSGSND: Joins the message to the end of the queue. MSGRCV: Fetching me

1. Set the content format of the generated xml to not wrap By default, the following code is used to create and generate xml:Copy codeThe Code is as follows:XmlDocument doc = new XmlDocument ();// Here is the code for creating nodes, omitting ....// SaveDoc. Save (filename );The generated nodes have line breaks: This will cause verification in xsd to fail. To avoid line breaks, doc. Save (filename); can be changed:Copy codeThe Code is as follows:Using (XmlTextWriter xtw = new XmlTextWriter (file

1. xsi IPC 1.1 identifier and key There are three types of IPC called xsi IPC, namely message queue, semaphores, and shared memory. The IPC structure (message queue, semaphore, and shared storage) in each kernel is referenced with a non-negative integer identifier (identifier. For example, to send or retrieve a message to a message queue, you only need to know its queue identifier. When an IPC structure is

The easiest way to do this is to use an overload of the serialize method. -- Stringwriter Sw = new stringwriter ();Xmltextwriter Tw = new xmltextwriter (SW );Xmlserializernamespcace xsn = new xmlserializernamespaces ();Xsn. Add (string. Empty, String. Empty );Xmlserializer serializer = new xmlserializer (typeof (myobject ));Serializer. serializer (TW, myobject, xsn ); According to reflector, the main serialize method checks if the xmlserializernamespace instance is null or has a zero length.

15.6 XSI IPC(1) 3 types of IPC known as XSI IPC are:1) Message Queuing2) Signal Volume3) Shared memory(2) Identifiers and keys1) Identifier: is a non-negative integer used to reference the IPC structure. is the internal name of the IPC object.2) Key: The external name of the IPC object. Enables multiple collaborative processes to converge on the same IPC object.(3) Ipc_private key:Used to create a new IPC s

Xmlns, xmlns: xsi Xmlns is the abbreviation of XML Namespaces. The Chinese name is The namespace of XML (a subset of standard General Markup Language. Cause For example: The following XML document carries the information in a table: Table Tr TdApples/td TdBananas/td /Tr /Table The following XML document carries information about the table (a piece of furniture ): Table NameAfrican Coffee Table/name Width80/width Length120/length /Table If the two XML

the first message in the message queue.>0-If the MSGFLG parameter does not contain a msg_except bit, the first message in the message queue of type Msgtyp is returned, and if the MSGFLG parameter contains a msg_except bit, the first message in the message queue that is not of type Msgtyp is returned.E. If there is a message queue that can receive messages, this function moves the message out of the message queue and returns 0 immediately, indicating that the receive succeeds, or the function bl
