Re: Using a UUID to name an IFS file

[Vernon Hamberg <vhamberg@xxxxxxxxxxx>]

A search at IBM iSeries support site for tmpnam 
brought me to the C/C++ runtime library manual - 
it's been around at least since v5r3 - simple 
function - pass it some character variable and 
get a temporary filename = up to 32767 in any 
activation group according to the docs.
