c/c++中用结构体作为参数传递给函数
[toc]
c语言中结构体的使用1定义结构体1234567struct Process{ wchar_t* name; int pid; int ppid; wchar_t* path;}_Process;
2使用结构体12345678910111213141516#include <stdio.h>struct Process{ wchar_t* name; int pid; int ppid; wchar_t* path;};int main(int argv, char* argc[]){ struct Process Info = {0}; Info.name = L"cmd.exe"; wprintf(L"name is %s\n", Info.name); return 0;}
