## Example main.c

```C

#include <stdio.h>

#include "sass/context.h"

int main( int argc, const char* argv[] )

{

  // get the input file from first argument or use default

  const char* input = argc > 1 ? argv[1] : "styles.scss";

  // create the file context and get all related structs

  struct Sass_File_Context* file_ctx = sass_make_file_context(input);

  struct Sass_Context* ctx = sass_file_context_get_context(file_ctx);

  struct Sass_Options* ctx_opt = sass_context_get_options(ctx);

  // configure some options ...

  sass_option_set_precision(ctx_opt, 10);

  // context is set up, call the compile step now

  int status = sass_compile_file_context(file_ctx);

  // print the result or the error to the stdout

  if (status == 0) puts(sass_context_get_output_string(ctx));

  else puts(sass_context_get_error_message(ctx));

  // release allocated memory

  sass_delete_file_context(file_ctx);

  // exit status

  return status;

}

```

### Compile main.c

```bash

gcc -c main.c -o main.o

gcc -o sample main.o -lsass

echo "foo { margin: 21px * 2; }" > foo.scss

./sample foo.scss => "foo { margin: 42px }"

```
