leaks, if the second malloc fails, the first allocated struct must be rolled back if it is divided by two allocations (struct and buffer). This brings a coding problem. Second, after assigning the second buffer, if the structure uses a pointer, the pointer is also assigned a value. Also, in the free buffer, use the pointer two times free. If an empty array is used, all problems are resolved at once. (2), s

lexical analysis of pl/0 language First, the purpose of the experiment Through the completion of lexical analysis procedures, understand the process of lexical analysis. Compile a read Word program, the lexical analysis of the pl/0 language, the input string form of the source program into a word symbol, that is, the basic reserved words, identifiers, constants, operators, the five major categories.

conflict risk. 　　One might suggest that there is no problem if the access to resources and the switching of resources are protected by the same lock . However, in the low frequency switching scenario, the lock brings the performance loss, some outweigh the gains. No lock 0/1 Toggle: Is there a lock-free switching method?

Windows File System filter driver development tutorial 0. Self-reported by Chu madman I have been playing the role of "technical implementer" for all project managers online for a long time. I feel that the development of Windows File System drivers can find less information. I have written this tutorial with my work experience in order to keep my technical experience away from forgetting and arouse your interest in communication. My understan

most basic knowledge about TensorFlow, including installation in other environments, GPU support, and so a little more complicated things are not mentioned. But in fact, the process from 0 to 1 is the biggest factor that has baffled many people. After understanding these things in the tutorial, I believe that understanding TensorFlow's official tutorial has no difficulty for you, if you follow the official
