It does not check the number of arguments. Follow the steps, there's nothing that rejects or checks it, and the shell doesn't examine your script to do that for you.
The number of arguments is available as a special variable "$#".

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.
