Manual pages for glibc.

Manual pages for glibc.

[Roel Janssen]

Dear Guix,

Which package do I need to install to be able to read the man pages of
functions in glibc like 'snprintf' and 'malloc'?

I installed glibc, but that does not seem to provide the man pages.

Kind regards,
Roel Janssen

Here’s what I did:

    unionfs $(printf "%s:" /gnu/store/*/share/info) ~/tmp/info

This gives me a union of all the beautiful info manuals in the store.
To read the GNU libc’s info manual I do this in Emacs:

   C-u C-h i ~/tmp/info/libc.info.gz RET

It opens up the manual and I can search for snprintf in the index with
“i snprintf RET”.

Not sure about the man pages, though.

Right.  Thanks for this solution.  On GuixSD, the info pages for libc
are automatically available in Emacs, so I can look up the functions
there.

It would still be nice to have the man-pages as well, because they are a
little more descriptive some times.

Kind regards,

Many man pages (including 'snprintf' and 'malloc') come with 'man-pages'
package.

Thanks!  That's what I was looking for!

This awkward solution should not be needed.  I simply installed
'gcc-toolchain' in my user profile and access the info manuals in Emacs
using C-h i.  Does that not work for you?

It’s not a solution in response to wanting to access libc; I did this
because I wanted to have access to all info manuals, regardless of
whether I have the packages in my profile or not.   I just like browsing
them.
