random functions tutorial?

I stupidly used random() and srandom() in my module to generate  
"random" filenames at high volume and, well, sigh.  Anyhow, the page  
at http://apr.apache.org/docs/apr/1.3/group__apr__random.html lacks  
tutorial value.  Anyone written up the *right* way to use these?  -T

Ignore all of them except apr_generate_random_bytes.

For making temp files, also consider apr_file_mktemp, with or without 
the APR_DELONCLOSE.
