This is a vim recipe for creating a function header automatically on a keystroke. For example, if you have a c function:

int foo (char *bar1, int bar2, struct uber bar3)
{
    ...
}

Running this with the cursor at or above the function will generate this header for you:

/*******************************************************************************
*   FUNCTION:  foo
*
*   ARGUMENTS: char *bar1, int bar2, struct uber bar3
*
*   DESCRIPTION:
*
*******************************************************************************/

Actual recipe:

function! FuncHdr()
        "Save current position
        let line_no = line(".")
        "Find the function
        normal ^
        "execute "norm! /^\\(\\w\\+[ :&*]\\{1,2}\\)\\+\\w\\+\\s*(\<CR>"
        execute "norm! /^[^(]*(.*\<CR>"
        execute "norm! /(\<CR>b"
        "echo getline(".")

        let fun_name = expand("<cword>")
        "echo fun_name
        let line_buff = ""
        while match(line_buff,")") == -1
                let line_buff = line_buff . getline(".")
                normal! j
        endwhile
        "echo line_buff
        "remove before bracket
        let args_list = substitute(line_buff, ".*(","","")
        "remove after bracket
        let args_list = substitute(args_list, ").*","","")
        "remove whitespaces
        let args_list = substitute(args_list, '\s\+'," ","g")
        "remove comments
        let args_list = substitute(args_list, '\/\*.*\*\/',"","g")
        "echo args_list
        execute "normal! :".line_no."\<CR>"
        execute "normal! A\<CR>\/\<Esc>"
        execute "normal! 79A*\<Esc>"
        execute "normal! A\<CR>  FUNCTION:  ".fun_name."\<Esc>"
        execute "normal! A\<CR>\<CR>ARGUMENTS: ".args_list."\<Esc>"
        execute "normal! A\<CR>\<CR>DESCRIPTION: \<Esc>"
        execute "normal! A\<CR>\<CR>\/\<Esc>h78i\*\<Esc>kkA"

endfunction

Lately, I was working on a new project, and had to create many .c and .h files. All the header files needed the #ifndef/#define/#endif boilerplating.
Being a lazy typist, following vim macro helped in generating the boiler-plating lines in the header files in a keystroke.

function! CHeader()
        "save the line location. This is for already existing files.
        let line_no = line(".")
        "Get the name of the file
        let fname = bufname(bufnr("%"))
        "get the name portion out
        let fname_root = toupper(fnamemodify(fname, ':r'))
        "get the extension
        let fname_extn = toupper(fnamemodify(fname, ':e'))
        if fname_extn != 'H'
                echo "Only applicable to header files"
        else
                "Create the macro name. This is what you need to change if you
                "want a different format.
                let define = "__".fname_root."_H"
                " Go to first line 0th column"
                execute "norm! :1\<CR>0"
                " Insert the #ifndef and #define
                execute "norm! i#ifndef ".define."\<CR>#define ".define."\<CR>\<Esc>"
                "Go to the last line column 0
                execute "norm! :$\<CR>0"
                "Insert the #endif statement
                execute "norm! i\<CR>#endif \/\*".define."\*\/\<Esc>"
                "Since we added two lines at the top, go to save line_no + 2
                let line_no = line_no + 2
                execute "normal! :".line_no."\<CR>"
        endif
endfunction
