For many major modes, that apply to languages that have documentation in
Info, you can use C-h S (info-lookup-symbol) to view the Info
documentation for a symbol used in the program. You specify the symbol with
the minibuffer; the default is the symbol appearing in the buffer at point.
For example, in C mode this looks for the symbol in the C Library Manual.
The command only works if the appropriate manual's Info files are installed.
The major mode determines where to look for documentation for the symbol—which Info files to look in, and which indices to search. You can also use M-x info-lookup-file to look for documentation for a file name.
If you use C-h S in a major mode that does not support it, it asks you
to specify the “symbol help mode.” You should enter a command such as
c-mode that would select a major mode which C-h S does support.
