how to display grep with multiple line

Question

I have the following code:

int val

nameof_function();

above code is in this file filename.txt I try to find that sequence of lines in a file using

grep "int val.*\n.*(" filename.txt

but it is not working with multiple line.

I have also tried

awk '/int val/,/\(/' filename.txt

Here i am not getting file name in output

If I am using grep I can find file name in output but not ble to search muliple line

I need an output that looks like this:

filename.txt:int val nameof_function

Please any one help me

Fix formatting and reword your question - it's hard to say what are you asking about. — Arkadiusz Drabczyk, Jan 30 '20 at 12:52
Personally I'd use pcregrep with the -M switch - however if that's not an option, see Searching match of multi-line regex in files (without pcregrep). You can access the current filename in awk using the FILENAME builtin variable. — steeldriver, Jan 30 '20 at 13:00
I tried to edit your post in a way that is more easy to understand, but ultimately it remains unclear e.g. what you mean by "Here i am not getting file name". Also, are you sure that the input is correct? It looks like C, but the int val statement is not terminated with a ; for example. — AdminBee, Jan 30 '20 at 13:01

if the source files contain the function separate by a line all you need to do is adjust the output of grep so it finds the int val and output the content 2 lines below also.

it would be something like this

grep -A 2 "int val" *.txt
