AssemblerEdit

CgEdit

Make the main program ( for CPU) in C, which loads and run the Cg program ( for GPU ).[1][2][3]

Header FilesEdit

Add to C program :[4]

#include <Cg/cg.h> /* To include the core Cg runtime API into your  program */
#include <Cg/cgGL.h>  /* to include the OpenGL-specific Cg runtime API */

JavaEdit

Using the Java native interface (JNI), Java applications can call C libraries.

PerlEdit

To mix Perl and C, we can use XS. XS is an interface description file format used to create an extension interface between Perl and C code (or a C library) which one wishes to use with Perl.

The basic procedure is very simple. We can create the necessary subdirectory structure by running "h2xs" application (e.g. "h2xs -A -n Modulename"). This will create - among others - a Makefile.PL, a .pm Perl module and a .xs XSUB file in the subdirectory tree. We can edit the .xs file by adding our code to that, let's say:

void
hello()
  CODE:
    printf("Hello, world!\n");

and we can successfully use our new command at Perl side, after running a "perl Makefile.PL" and "make".

Further details can be found on the perlxstut perldoc page.

PythonEdit

Here can be found some details about extending Python with modules written in C. You might read about Cython and Pyrex as well, that makes easier to create modules in C, translating a Python-like code into C.

Using the Python ctypes module, one can write C code directly into Python.
