No, the only thing you've done there is show how to nest blocks.

In Pascal (or Borland Pascal, at least) you can define an entire procedure
inside another one, meaning you could have two
functions/procedures with the same name in the same source module, provided
they were enclosed in their own individual "wrapper"
functions/procedures.  C doesn't support this, and the closest you'll get
to these sorts of "private" functions is declaring a function as
"static", meaning that it can't be accessed by other modules in
your application, eg.


   -+- test1.c -+-

#include 

void callAnotherMyFunc(void);

static void myFunc(void)
{
    printf("Hello from %s\n", __FILE__);
}

int main(void)
{
    myFunc();
    callAnotherMyFunc();
    return 0;
}


   -+- test2.c -+-

#include 

static void myFunc(void)
{
    printf("Hello from %s\n", __FILE__);
}

void callAnotherMyFunc(void)
{
    myFunc();
}


   -+-

randy{at}snoopy:/main/home/randy$gcc -o test test1.c test2.c

randy{at}snoopy:/main/home/randy$test
Hello from test1.c
Hello from test2.c


The following won't compile though, since the standard doesn't support it ...

   -+- test.c -+-

#include 

int main(void)
{
    void myFunc(void)
    {
    	printf("Hello from the inside.\n");
    }

    myFunc();
    printf("Hello world.\n");
    return 0;
}


   -+-
