variables, and the parent process has also seen this modification. The vfork function may occur because the fork of the early system did not implement the write-time replication technology, resulting in a lot of useless work in each fork call (in most cases, it is called exec to execute a new program after fork) the efficiency is not high, so the vfork function is created. The current implementation basically uses the write-time replication technology, and when the vfork function is used improp

That is, the child node is a text node.

This is a detailed tutorial on iOS block. I have searched official documents and can understand them in poor English. Slow speed. Later, I found the translation of most of the above documents and thought it was quite good. For block learning. Roughly divided into several points 1. SDK restrictions, that is, the version of the block to which the new feature is introduced. 2. Basic syntax 3. Scenario use. I. Block description Block is a new program synt

Moreover, "C plus good design" can also write very good things.The importance of the C language before, because it starts from the bottom (such as the string is very primitive, you can let you know the source of the string) to show you the idea of process-oriented p
