When to define functions in C?

Hey everyone. So I'm looking at a few C programming resources, and it seems, by convention how you should write and define a function, is first declare it's existence before your main...then call it somewhere in your main, and then define after, at the end of the program? Is this necessary? I mean...

NAME

       Alzabo::Runtime::JoinCursor - Cursor that returns arrays of "Alzabo::Runtime::Row" objects

SYNOPSIS

	 use Alzabo::Runtime::JoinCursor;

	 my $cursor = $schema->join( tables => [ $foo, $bar ],
				     where => [ $foo->column('foo_id'), '=', 1 ] );

	 while ( my @rows = $cursor->next )
	 {
	     print $rows[0]->select('foo'), "
";
	     print $rows[1]->select('bar'), "
";
	 }

DESCRIPTION

       Objects in this class are used to return arrays of Alzabo::Runtime::Row objects when requested.	The cursor does not preload objects but
       rather creates them on demand, which is much more efficient.  For more details on the rational please see the RATIONALE FOR CURSORS section
       in Alzabo::Design.

INHERITS FROM

       "Alzabo::Runtime::Cursor"

METHODS

       next

       Returns the next array of "Alzabo::Runtime::Row" objects or an empty list if no more are available.

       If an individual row could not be fetched, then the array may contain some "undef" values.  For outer joins, this is normal behavior, but
       for regular joins, this probably indicates a data error.

       all_rows

       This method fetches all the rows available from the current point onwards.  This means that if there are five set of rows that will be
       returned when the object is created and you call "next()" twice, calling "all_rows()" after it will only return three sets.

       The return value is an array of array references.  Each of these references represents a single set of rows as they would be returned from
       the "next" method.

       reset

       Resets the cursor so that the next "next()" call will return the first row of the set.

       count

       Returns the number of rowsets returned by the cursor so far.

       next_as_hash

       Returns the next rows in a hash, where the hash keys are the table names and the hash values are the row object.  If a table has been
       included in the join via an outer join, then it is only included in the hash if there is a row for that table.
