Calling C Functions

Monga can use C functions.

These functions must be declared in monga, and defined in C.

Standard C functions can be used by simply be declared:

int exit(int number); //will render C exit usable

You can also use your own C functions, for example

char[] readFile(char[] filename); // monga source

//(...)
char[] fileStr;
fileStr = readFile("input.txt");

In C this function its something like this

char * readFile(char* path)
{
int size;
FILE * input;
char * fileString;
    //(...) 
    return fileString;
}

However, in order to be used in monga, these C functions must be able to be declared in monga

Anything that uses void* , structured types or elipses cannot be declared in monga.

Some notable examples are printf(), scanf(), fprintf() and fscanf().

Note that you will need clang to compile C functions to LLVM to use this feature, since MongaComp isn't a C compiler.
