一、函數聲明

#include <sys/stat.h>
#include <sys/types.h>
int mkdir(const char *pathname, mode_t mode);

#include <fcntl.h>           /* Definition of AT_* constants */
#include <sys/stat.h>
int mkdirat(int dirfd, const char *pathname, mode_t mode);

#include <unistd.h>
int rmdir(const char *pathname);
// rmdir() deletes a directory, which must be empty.
           

二、執行個體

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

int main(int argc, char **args)
{
    if (mkdir("hotice0", S_IRWXU|S_IRWXG|S_IXOTH|S_IROTH) < 0) {
        perror("mkdir");
        exit(EXIT_FAILURE);
    }
    printf("hotice0 directory is created\n");
    sleep(5);
    if (rmdir("hotice0") < 0) {
        perror("rmdir");
        exit(EXIT_FAILURE);
    }
    printf("hotice0 directory is removed\n");
    return 0;
}
