问题
I want an easy way to create multiple directories in C.
For example I want to create directory in:
/a/b/c
but if the directories are not there I want them to be created automagically. How can I do this ?
回答1:
Here is a small C program to create the directory tree a/b/c
in the current directory:
#include <stdio.h>
#include <stdlib.h>
#include <sys/stat.h>
#include <errno.h>
int create_dir(char *name)
{
int rc;
rc = mkdir(name, S_IRWXU);
if (rc != 0 && errno != EEXIST)
{
perror("mkdir");
exit(1);
}
if (rc != 0 && errno == EEXIST)
printf("%s already exists.\n", name);
return 0;
}
int main(int argc, char **argv)
{
create_dir("a");
create_dir("a/b");
create_dir("a/b/c");
exit(0);
}
