Redis Source Analysis (32)---REDIS-CLI.C implementation of client command line interface (1)

Analysis of the Redis source code for nearly 1 months, but also to the most core, closest to the beginning of the system, I named him the main directory, which included 2 important documents, REDIS-CLI and Redis files, 1 represents the client's execution file, 1 represents the service-side file, these 2 are also the system's most core modules, so I put him down to main main program module, the main program module is also my Learning Redis the last module, here will be able to see all the features I saw before the traces of all the modules. Because the code in the main module is much more, so I chose a batch of learning, so today I mainly put the inside of the API method to pull out, the redis-cli of things, did an anatomy.

Just beginning to think REDIS-CLI. is the abbreviation of redis-client, but in fact he means:

/* Redis CLI (
 command line interface) * Command-Line interface

So, he is directly responsive to the operation of the Redis under the Black Window command. In this file, you define the Redis context, configure the information structure, and a bunch of APIs, which are roughly the same:

/* Redis context
/static rediscontext *context;
/* REDIS configuration structure body/
static struct config

Mainly behind the various APIs, do not rush to see the method, because the method is really too much, first we learn to classify: The following is a map I do;

The module is still quite a lot of bar above are the expression form of English, in the follow-up analysis, I will be a module to do the study, such as the first Utility functions is the meaning of the general method, and what the following methods and so on.
