從不兼容的指針類型和解引用指針到不完整類型的指派<dirent.h>

Question

我正在嘗試編寫程序來讀取它所在程序所在的文件夾的相關信息。我在其他在線源中檢查了一倍，並且它看起來像我正在使用與其他正確的解決方案相同的模式（見下文）。

#include <stdio.h> 
#include <string.h> 
#include <stdlib.h> 
#include <sys/types.h> 
#include <sys/stat.h> 
#include <unistd.h> 
#include <dirent.h> 

void append(char* path, char* cur) 
{ 
    strcat("/",cur); 
    strcat(cur,path); 
} 

void addDot(char* dot) 
{ 
    int len = strlen(dot); 
    dot[len] = '.'; 
} 

int main() 
{ 
    struct stat st; 
    int stDevCur = st.st_ino; 
    int stDevNew = 0; 
    int inodeCur = st.st_dev; 
    int inodeNew = 0; 
    char* path = ""; 
    char* new = ""; 
    char* cur = "_"; 
    char* dot = "."; 
    DIR* dir; 
    struct dirnet* file = NULL; 

    if((dir = opendir(dot)) == NULL) 
    { 
     perror(NULL); 
     exit(EXIT_FAILURE); 
    } 
    while(strcmp(cur,new) != 0) 
    { 
     if((file = readdir(dir)) == NULL) 
     { 
      perror(NULL); 
      exit(EXIT_FAILURE); 
     } 
     while(file != NULL) 
     { 
      inodeNew = st.st_ino; 
      stDevNew = st.st_dev; 
      if(inodeNew == inodeCur && stDevNew == stDevCur) 
      { 
       cur = file->d_name; 
       append(path, cur); 
       break; 
      } 
     } 
     fprintf(stderr,"%s\n",path); 
    } 
    return 0; 
} 

提供了以下錯誤

main.c: In function ‘main’: 
main.c:42:16: error: assignment from incompatible pointer type [-Werror] 
     if((file = readdir(dir)) == NULL) 
       ^
main.c:53:23: error: dereferencing pointer to incomplete type 
     cur = file->d_name; 
       ^
cc1: all warnings being treated as errors 
make: *** [main.o] Error 1 

我一直在尋找這一點，因爲昨晚已在它們具有類似的問題在計算器

Answer 1

struct dirnet* file = NULL; 

比較的問題是一個拼寫錯誤。它應該是：

struct dirent* file = NULL;
