Use-DEBUG for code debugging

Recently, I was writing a linux c program. Because it is based on someone else's WebKit project, debugging is really troublesome. Every time I modify it, I need to compile the library, which is slow. A lot of information is printed, and it is useless to delete one item after debugging. After deletion, it is found that you still need to print those deleted items, after learning about debugging, we can get a better Debugging Technique: Define DEBUG.

The method is to first define various debugs, such as # define DEBUG_FILTER = 2;

Then, if you want to debug the filter, you can use

[Cpp]
# Ifdef DEBUG
If (DEBUG & DEBUG_FILTER ){
// Show some debug info
}
# Endif
Compile with the parameter-DEBUG = 2. This method can achieve a variety of debugging operations, which is very convenient.
