mkdtemp: vytvořit jedinečný dočasný adresář

Originální popis anglicky: mkdtemp - create a unique temporary directory

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <stdlib.h>
 
char *mkdtemp(char *template);

POPIS / INSTRUKCE

The mkdtemp() function generates a uniquely-named temporary directory from template. The last six characters of template must be XXXXXX and these are replaced with a string that makes the directory name unique. The directory is then created with permissions 0700. Since it will be modified, template must not be a string constant, but should be declared as a character array.

NÁVRATOVÁ HODNOTA

The mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case errno is set appropriately.

CHYBY / ERRORY

EINVAL

The last six characters of template were not XXXXXX. Now template is unchanged.

 

Also see mkdir(2) for other possible values for errno.
