echo $LINENO to display line number how to do that for functions ? shell scripting

Hello all,
Within a shell script ( linux ) echo $LINENO gives the line nubmer.
Is there a way to get the name of the function that is currently called ?

That is
I have sth like

function dinesh_p_v()
{
echo $LINENO
echo dinesh_p_v
#some stuff
}

function dins()
{
echo $LINENO
echo dins
#some stuff
}

function dinesh()
{
echo $LINENO
echo dinesh
#some stuff
}


This displays the line number and function name which is hardcoded. Instead I need to display the function name without hardcoding it.

Is there a way to achieve this

Thanks in advance,
Murugesan
