"MAN" Manual?

[TieFighter]

When I ask some people for help in C code they ask if I've checked the man entry for the function. It seems to be a Unix command line argument - and I've sucessfully been able to pull up entries for various other command line programs with things like

penguin@penguin-laptop:~$man LS
penguin@penguin-laptop:~$man GCC

The GCC man gives me 13688 lines of options that I can add after typing gcc, but nothing for individual functions in the libraries of C that I'm looking for.

Does anyone know how to find manual entries for functions in C libraries?

This should work if you have the man pages installed:

man function

man header

For example:

man printf

man stdio

[TieFighter]

penguin@penguin-laptop:~$ man malloc
No manual entry for malloc
penguin@penguin-laptop:~$ man memcpy
No manual entry for memcpy
penguin@penguin-laptop:~$ man memmove
No manual entry for memmove

So, how would I go about installing the manual file for the GCC libraries?

I'm guessing you're using Ubuntu, so install libc6-dev.

Yes. I am using Ubuntu. Unfortunately libc6-dev was already installed and it still wasn't displaying manual pages for C functions. I poked around with a search engine quick after you mentioned I probably didn't have the man pages installed and found these manuals to install:

Install manpages, manpages-dev, manpages-posix, manpages-posix-dev.

sudo apt-get install manpages manpages-dev manpages-posix manpages-posix-dev

That seemed to work. Thank you for pointing me in the right direction though - I thought that the manual would have been installed already since gcc was installed.

Or you can view it in the browser in a much more user friendly GUI by typing "man whatever" in google.
