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

#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;
}
