Header File

dir.h

Category

Directory Control Routines

Prototype

int mkdir(const char *path);

int _wmkdir(const wchar_t *path);

Description

Creates a directory.

mkdir is available on UNIX, though it then takes an additional parameter.

mkdir creates a new directory from the given path name path.

Return Value

mkdir returns the value 0 if the new directory was created.

A return value of -1 indicates an error, and the global variable errno is set to one of the following values:

EACCES | Permission denied
ENOENT | No such file or directory

Example

Copy Code

    #include <stdio.h>
    #include <process.h>
    #include <dir.h>
    #define DIRNAME "testdir.$$$"
    int main(void)
    {
        int stat;
        stat = mkdir(DIRNAME);
        if (!stat)
               printf("Directory created\n");
        else
        {
           printf("Unable to create directory\n");
           exit(1);
        }
        getchar();
        system("dir/p");
        getchar();
        stat = rmdir(DIRNAME);
        if (!stat)
               printf("\nDirectory deleted\n");
        else
        {
               perror("\nUnable to delete directory\n");
           exit(1);
        }
        return 0;
    }
