At some point you have to assume some level of knowledge and knowing how to read a man-page either via the web or from the CLI I would expect people who are asking programming questions to know. If they don't they only have to ask.

On my slackware box the page is in section 2, system call not library function, though a simple 'man wait' without any section pops it straight up.

Thanks. I didn't pay enough attention to the meanings of the sections in man.

Google led me to believe it was in section 3.

Simply using man wait on any of my systems pulls up only the BASH_BUILTINS wait in section 1.

man 3 wait doesn't work for me (despite what I got from google). But man 2 wait (based on the info you just provided) works.

I wasn't suggesting you were wrong to tell the OP to read the man page without telling him how. I was just guessing at why he might have failed to follow that suggestion then asked a follow-up question that was answered by that man page.

No worries John. Slackware has its share of missing man-pages too, so I end up using linux.die.net from time to time myself, it's a good place to have bookmarked
