3. Differences between const int *, int const *, int * const, const int * const, and INT const * const
The best difference is to read the variable declaration from the back, as shown in the following English after the comment:Int x = 10;Const int * P1 = X; // P1 pointsA integer that is const // The value of X cannot be changed through P1, that is, * P1 = 5 will produce a compilation error. Int const * P2 = X;//
problem as follows:
If both statements are accurate or on-demand, compilation errors may occur.
If a statement adopts the exact import mode and the on-demand import mode, the exact import mode is effective.
NOTE: If two static members with the same name are attributes and the other is methods, there will be no conflicts because of the differences in the writing method during use.Listing 4: a valid package com. example. P4 in the form of precise i

-2 compression encoding, this data stream is very large, and only the I, P, B of these video frame or audio sampling information, then add some synchronization information and package it into a variable-length data packet PES. It turns out to be a stream format and is now a form of data packet segmentation. At the same time, it should be noted that ES is a data stream that only contains one type of content, such as only video or only audio. the packaged PES also only contain one type of Es, for

you already understand the basic configuration of Nginx, then uwsgi is similar to this Configuration:
location/{

}
This is to send all URLs to the uwsgi Protocol Program on port 9090 for interaction. Create myapp. py in the project directory so that the application calls the wsgi interface of the Framework. For example, web. py is:
......
app=web.application(urls,globals())
