“In computer programming, data types can be divided into two categories: A value of value type is the actual value. A value of reference type is a reference to another value。 定义中把数据类型分为值类型和引用类型两类,然后介绍 值类型的值是信息本身;引用类型来的值是引用,这个引用可以为 nil,...

osscan.cc:主要负责os指纹的解析、对比函数,可直接看如下的函数定义。 /* Parses a single fingerprint from the memory region given. If anon-null fingerprint is returned, the user is in charge of freeing itwhen done. This function does not require the fingerprint to be 100%complete since it is...
Golang - Map 内部实现原理解析 一.前言 Golang中Map存储的是kv键值对,采用哈希表作为底层实现,用拉链法解决hash冲突 本文Go版本:gov1.14.4,源码位于src/runtime/map.go 二.Map的内存模型 在源码中,表示map的结构体是hmap,是hashma

I encountered this issue on macOS while importing two Python extensions written in Go usingPygolo. I could reduce the problem to the following repro, completely removing Python from the picture. This is a minimal shared library exporting a dummy function: ...
The command line name for each parameter, along with the default values and simple function descriptions are as follows:--kcp-key="secrect" pre-shared secret between client and server --kcp-method="aes" encrypt/decrypt method, can be: aes, aes-128, aes-192, salsa20, blowfish, Twofish, ...
