Name

ns_mktemp - Make a unique temporary file name

Table Of Contents

Synopsis

Description

This command is a wrapper around the mktemp(3) function in the C standard library. It takes a template, which is a string whose last six characters must be XXXXXX, and returns a new string where those are replaced with random characters such as to make the string a unique file name. It is commonly used to safely create temporary files.

Note that some implementations of mktemp are not so safe - it creates predictable/only a small number of variations - please consult your system's man pages if this might be an issue to you. NaviServer could potentially be improved to use mkstemp instead.
