Searching For a String Stored in a Register From Within a Function

Question

If I have something stored in the named register n, then from the normal mode hitting

/<C-R>n

would search for what is stored inside the register.

But suppose I want to write a function which searches for what is stored in the n register. What do I do?

I tried

function! SearchTheDataInnReg()
   <C-R>l
endfunction

I get an error message:

E488: Trailing characters: <09><C-R>l

Answer 1

From function you can access to named registers via @. For explanation :he let-@ and similars topics. For search pattern call search() function.

Your code may look like this. In this example we search pattern in l register.

func! SearchTheDataInnReg()
    call search(@l)
endfunc
