NAME

mktemp - make a unique filename

 SYNOPSIS

#include <stdlib.h>

char *mktemp(char *template);

 DESCRIPTION

The mktemp() function replaces the contents of the string pointed to by template by a unique filename and returns template. The application must initialise template to be a filename with six trailing 'X's; mktemp() replaces each 'X' with a single byte character from the portable filename character set.

 RETURN VALUE

The mktemp() function returns the pointer template. If a unique name cannot be created, template points to a null string.

 ERRORS

No errors are defined.

 EXAMPLES

None.

 APPLICATION USAGE

Between the time a pathname is created and the file opened, it is possible for some other process to create a file with the same name. The mkstemp() function avoids this problem.

For portability with previous versions of this document, tmpnam() is preferred over this function.

 FUTURE DIRECTIONS

None.
