Although /dev/zero can be used this way on most systems, the conventional device for dumping output into the trash can is /dev/null which is described by the standards as:
The standards do not require systems to provide /dev/zero.

mktemp
mktemp(3C) Standard C Library Functions mktemp(3C)NAME
mktemp - make a unique file name from a template
SYNOPSIS
#include <stdlib.h>
char *mktemp(char *template);
DESCRIPTION
The mktemp() function replaces the contents of the string pointed to by template with a unique file name, and returns template. The string
in template should look like a file name with six trailing 'X's; mktemp() will replace the 'X's with a character string that can be used to
create a unique file name. Only 26 unique file names per thread can be created for each unique template.
RETURN VALUES
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
Example 1 Generate a filename.
The following example replaces the contents of the "template" string with a 10-character filename beginning with the characters "file" and
returns a pointer to the "template" string that contains the new filename.
#include <stdlib.h>
...
char *template = "/tmp/fileXXXXXX";
char *ptr;
ptr = mktemp(template);
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(3C) function avoids this problem and is preferred over this function.
