I already have a list of available C programs which are being used with R here, https://svn.r-project.org/R/trunk/src/main/. However this list does not contain above C function.

Try this:

  https://svn.r-project.org/R/trunk/src/library/stats/src/approx.c

You'll find code for both approxtest and approxfun.
