executed concurrently, it loses its reproducibility due to the loss of its closeness. may produce different results due to different sequence of operations. The characteristics of the 2.3 process because they lose their closeness, discontinuity, and non-reproducibility due to program concurrency, this determines that a generic program cannot participate in concurrent execution because the results of the program execution are not reproducible. In this way, the operation of the program is mean

quarter.Q: Has pspice function changed?A: In the new version of protel, the simulation function will be greatly improved.Q: Will the Chinese version of protel dxp be available now?Reply: No.Q: How can I lock the first line before automatic cabling ?? One by one?A: The pre-wiring locking function in 99se is good. You don't have to select one by one. You just need to click a check box in the auto-wiring settings.Q: How can different net in the pcb be c
meaning. It is a static concept. A process is an execution process of a program on the processing machine. It is a dynamic concept.
The existence of programs is permanent. A process has a life cycle. It is created and executed due to scheduling. It is suspended due to lack of resources and disappears due to cancellation.
A program is only an ordered set of commands. A process consists of a program segment, a related data segment, and a process control block (

Introduction
LWIP provides two APIs:
1. Underlying callback-based raw API
2. High-level ordered model APIs (similar to BSD socket)
The ordered model API provides APIs that use protocol stacks for Common Ordered programs. Similar to BSD APIs, it is also based on the blocked open-read-write-close mode. The TCP/IP protocol stack is time-based. Therefore, TCP/IP code and application code must be in different threads.
The raw API can make the application and TCP/IP protocol stack code more closely in
