Is it possible to call the function available in .obj code?

Is it possible to call the function available in .obj code?
Solution:
===========
yes.
But We can use it only in C file;In C++, we need further information;
I have developed the DLL project;
Within c file, We are able to call the function in obj code;
So within that DLL project, I have added the following
int ScaleRGB(int Width,int Height); available in object code;

Header.c:
--------
void ScaleRGB_Wrapper(int Width,int height)
{
ScaleRGB(width,height);
}
we have to add the .obj file to our DLL project;
within C code , call this ScaleRGB() fn and export the ScaleRGB_Wrapper() fn
as follows:
TESTDLL_API void ScaleRGB_Wrapper(int Width,int height)
{
ScaleRGB(width,height);
}
From the DLL client C++ application, call the ScaleRGB_Wrapper() function in a DLL;
