Showing C Function Headings
...........................
To show in which functions differences occur for C and similar
languages, you can use the `-p' or `--show-c-function' option. This
option automatically defaults to the context output format (
Context Format), with the default number of lines of context. You
can override that number with `-C LINES' elsewhere in the command line.
You can override both the format and the number with `-U LINES'
elsewhere in the command line.
The `-p' and `--show-c-function' options are equivalent to `-F
'^[[:alpha:]$_]'' if the unified format is specified, otherwise `-c -F
'^[[:alpha:]$_]'' ( Specified Headings). GNU `diff' provides
them for the sake of convenience.
