我正在使用下面的代码将文件名保存到数组中。我从这里得到的代码将文件名保存到一个数组中。当我运行这段代码时,它说目录中有 5 个文件(即count
5 个),但是,只有 3 个。有人可以验证这是否正确还是我犯了一个严重的错误?
#include <string.h>
#include <stdio.h>
#include <dirent.h>
#include <malloc.h>
size_t file_list(const char *path, char ***ls) {
size_t count = 0;
size_t length = 0;
DIR *dp = NULL;
struct dirent *ep = NULL;
dp = opendir(path);
if(NULL == dp) {
fprintf(stderr, "no such directory: '%s'", path);
return 0;
}
*ls = NULL;
ep = readdir(dp);
while(NULL != ep){
count++;
ep = readdir(dp);
}
rewinddir(dp);
*ls = calloc(count, sizeof(char *));
count = 0;
ep = readdir(dp);
while(NULL != ep){
(*ls)[count++] = strdup(ep->d_name);
ep = readdir(dp);
}
closedir(dp);
return count;
}
int main(int argc, char **argv) {
char **files;
size_t count;
int i;
count = file_list("/home/rgerganov", &files);
for (i = 0; i < count; i++) {
printf("%s\n", files[i]);
}
}
