linux C 获取当前目录的实现:
//获取当前目录
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <unistd.h> //包含了Linux C 中的函数getcwd()
#define FILEPATH_MAX (80)
int main(){
char *file_path_getcwd;
file_path_getcwd=(char *)malloc(FILEPATH_MAX);
getcwd(file_path_getcwd,FILEPATH_MAX);
printf("%s",file_path_getcwd);
}
