How to call .pyc function from C or C++?

I have .pyc files I know functions inside it.

I need to call those function from C/ C++ I tried using PyImport_Import but it returns NULL.

pName = PyString_FromString("test");
pModule = PyImport_Import(pName );

if I call pModule = PyImport_ImportModule("py_ffile"); then it's working fine for .py files. But I don't want to call function from .py. I want to call it from .pyc file.

The path where your py file is located could be unknown. Trying to add your path by using sys like this, if you are using Boost Python:

PyRun_SimpleString("import sys"); 
PyRun_SimpleString("sys.path.append(\"your path here\")");

or use this one:

PySys_SetPath("your path here");

And like this, if you are using directly the python dll:

SetSysPath("your path here");

and then try again with PyImport_Import

This is not exactly what you are asking for, but you could consider using Cython. It will compile your code to C, and you'll have no problem to use it from a C++ program.
