No manual entry for fcntl problem

Question

When I use `man fcntl' got the message:

No manual entry for fcntl

which the pkg is needed to install?

ps. I use debian.

Answer 1

In Debian these man pages are available in manpages-dev package.

Answer 2

This doesn't answer your question directly, but: I myself just use the internet: here is the first search result for "man fcntl" in google.

Answer 3

fcntl is a standard C library function so it should be one of your development packages. However, I long ago gave up on using man on the UNIX boxes themselves, try typing "man fcntl" into Google (with the quotes) to get online versions.

Just don't do this to try and figure out how man itself works. Typing "man man" into Google returns some interesting results (not safe for work).
