I remember having the same issues when I was sorting my skills list.. the srt_helps is where your problem lies.
use this as your NULL check. ---------------------------------------------- if (help1.keyword == NULL) return 1; else if (help2.keyword == NULL) return -1; ---------------------------------------------- That should solve your problem. -V ----- Original Message ----- From: "Dale Kingston" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, January 28, 2004 1:50 AM Subject: Qsort > Ok question/problem, I had qsort sort my helpfiles.
