Test case design is one of the basic skills that testers must master, and it is also one of the difficulties. So how does a written test case evaluate effectiveness? Recently has been thinking about this issue, originally wanted to come to an article, but has been lazy, until now, the information on the Internet a lot, here on the combination of their own thinking to simply talk about their own views it. 1, from the test case form analysis First, each

): The function allocates numbytes bytes and returns a pointer to the memory. If the allocation fails, an empty pointer (NULL) is returned. There should be a variety of reasons for allocation failure, such as lack of space. void free (void *firstbyte): The function is to return the space previously allocated by malloc to the program or the operating system, that is, to release the memory and let it regain its freedom. 2, the use of the function:

, and host class. In P2P technology, UPnP is often used to implement direct TCP transfer, but different devices have small differences, and the methods supported by different devices are not the same, in the process of software startup, in order to save system overhead and synchronization, the Timer class is used to realize the addressing and interaction of UPnP. Experienced software developers know that

This article is to New/delete and malloc/free these two pairs of use and the difference comparatively simple analysis, for eve

The technology of rogue software is varied. Any function may become a rogue technology, just like a weapon. If it is used, justice can be done. If it is used properly, it can be used as an accomplice to evil. First, I started with some rogue Analysis in win32: 1. As a rogue software, the first thing I want to do is to run it in real time. For example, in the regi
