Syntax

#include <direct.h>
int mkdir(char *pathname);

mkdir creates a new directory with the specified pathname. Because only one directory can be created at a time, only the last component of pathname can name a new directory.

mkdir returns the value 0 if the directory was created. A return value of -1 indicates an error, and errno is set to one of the following values: compact break=fit.

Value

Meaning
EACCESS
The directory was not created; the given name is the name of an existing file, directory, or device.
ENOENT
The pathname was not found.

This example creates two new directories: one at the root on drive C:, and one in the tmp subdirectory of the current working directory.

#include <stdio.h>#include <direct.h>
#include <string.h>

int main(void)
{
   char *dir1,*dir2;

 /*  Create the directory "aleng" in the root directory of the C: drive.      */

   dir1 = "c:\\aleng";
   if (0 == (mkdir(dir1)))
      printf("%s directory was created.\n", dir1);
   else
      printf("%s directory was not created.\n", dir1);

 /*  Create the subdirectory "simon" in the current directory.                */

   dir2 = "simon";
   if (0 == (mkdir(dir2)))
      printf("%s directory was created.\n", dir2);
   else
      printf("%s directory was not created.\n", dir2);

 /*  Remove the directory "aleng" from the root directory of the C: drive.    */

   printf("Removing directory 'aleng' from the root directory.\n");
   if (rmdir(dir1))
      perror(NULL);
   else
      printf("%s directory was removed.\n", dir1);

 /*  Remove the subdirectory "simon" from the current directory.              */

   printf("Removing subdirectory 'simon' from the current directory.\n");
   if (rmdir(dir2))
      perror(NULL);
   else
      printf("%s directory was removed.\n", dir2);
   return 0;
