After reading the gif file format, we can see that the data blocks are compressed using the lzw algorithm.
So I implemented one by myself according to the algorithm described in it. It took three days, and now I am not focused, and the speed of code implementation is also very slow.
On the first day, I read the algorithm and compiled the compression function. After checking it on paper, the encoding for small data volumes is consistent with that for manual computation.
The next day, I wrote so

In addition, WWF, WCF, WPF, and officesystem belong to the technical scope of C. So, I can't find anyone in th

In addition, for many frameworks, you can check the version of the specified Framework at runtime. Example: Application Kit (NSApplication. h) defines the NSAppKitVersionNumber constant. It can be used to check the version of the Application Kit Framework, for example •. APPKIT_EXTERN double NSAppK

Why cannot the socket with TCP_NODEALY be recovered after the network is ready?
Let's look at the implementation of the recv system call (2.6.9 kernel), which is traced back to the tcp_recvmsg function:
