在c中创建文件及其父目录 [英] Create a file and its parents directories in c

问题描述

我没有找到与此问题相关的答案.

I didn't find any relevant answer for this question.

我想同时创建一个文件及其父目录:

I want to create a file and its parent directory at the same time:

示例:

FILE *fd2 = fopen("test/test", "w+");

不存在test/的地方.

where test/ doesn't exist.

有没有办法做到这一点?

Is there a way to do this?

推荐答案

在Linux中，您可以使用以下代码完成

In Linux you can do it with the following code

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
... 
/* check if directory exist */
struct stat status = { 0 };
if( stat("test", &status) == -1 ) {
  /* create it */
  mkdir( "test", 0700 );
}
/* open file */
FILE *fd2 = fopen("test/test", "w+");
... 

对于第一个if语句中存在文件test(stat返回值为零)的情况，您还可以使用宏S_ISREG和S_ISDIR来检查这是文件还是目录. stat结构的字段st_mode.

For the situation when file test exists in first if statement (stat return value is zero), you can also check if this is a file or a directory using macros S_ISREG and S_ISDIR and field st_mode of stat struct.
