Other Commands for C Mode
-------------------------
`C-M-h'
Put mark at the end of a function definition, and put point at the
beginning (`c-mark-function').
`M-q'
Fill a paragraph, handling C and C++ comments (`c-fill-paragraph').
If any part of the current line is a comment or within a comment,
this command fills the comment or the paragraph of it that point
is in, preserving the comment indentation and comment delimiters.
`C-c C-e'
Run the C preprocessor on the text in the region, and show the
result, which includes the expansion of all the macro calls
(`c-macro-expand'). The buffer text before the region is also
included in preprocessing, for the sake of macros defined there,
but the output from this part isn't shown.
When you are debugging C code that uses macros, sometimes it is
hard to figure out precisely how the macros expand. With this
command, you don't have to figure it out; you can see the
expansions.
`C-c C-\'
Insert or align `\' characters at the ends of the lines of the
region (`c-backslash-region'). This is useful after writing or
editing a C macro definition.
If a line already ends in `\', this command adjusts the amount of
whitespace before it. Otherwise, it inserts a new `\'. However,
the last line in the region is treated specially; no `\' is
inserted on that line, and any `\' there is deleted.
`M-x cpp-highlight-buffer'
Highlight parts of the text according to its preprocessor
conditionals. This command displays another buffer named `*CPP
Edit*', which serves as a graphic menu for selecting how to
display particular kinds of conditionals and their contents.
After changing various settings, click on `[A]pply these settings'
(or go to that buffer and type `a') to rehighlight the C mode
buffer accordingly.
`C-c C-s'
Display the syntactic information about the current source line
(`c-show-syntactic-information'). This is the information that
directs how the line is indented.
`M-x cwarn-mode'
`M-x global-cwarn-mode'
CWarn minor mode highlights certain suspicious C and C++
constructions:
* Assignments inside expressions.
* Semicolon following immediately after `if', `for', and `while'
(except after a `do ... while' statement);
* C++ functions with reference parameters.
You can enable the mode for one buffer with the command `M-x
cwarn-mode', or for all suitable buffers with the command `M-x
global-cwarn-mode' or by customizing the variable
`global-cwarn-mode'. You must also enable Font Lock mode to make
it work.
`M-x hide-ifdef-mode'
Hide-ifdef minor mode hides selected code within `#if' and
`#ifdef' preprocessor blocks. See the documentation string of
`hide-ifdef-mode' for more information.
`M-x ff-find-related-file'
Find a file "related" in a special way to the file visited by the
current buffer. Typically this will be the header file
corresponding to a C/C++ source file, or vice versa. The variable
`ff-related-file-alist' specifies how to compute related file
names.
