In general what you want to do cannot be done without actually writing a parser that understands all of the complexities of the C language. The single line that you are looking for:
could appear anywhere within a line of C source code (not necessarily starting in position 1 nor ending at the end of a line and could include the return code type and the body of the function in addition to what you have shown, or could be spread across hundreds of lines of C source code before it gets to the body of the function definition.
Even if the group writing the kernel, utility, library, or single function you're looking for has strict function coding rules, there are occasionally exceptions that will be granted for various reasons for various functions.

echo "function within test shell script "

test_fn()
It echos the line
function within test shell script
and works as expected.

script - make record of a terminal session
SYNOPSIS
script [-a] [filename]
DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.
