inline-compile STRING #!optional OPTIONSprocedure

Compiles the C source code in STRING dynamically. If a compiled library with the same source text is currently loaded (and has been cached), then nothing is done. If it is not loaded, the inline cache is consulted, whether a compiled file for the same text is stored, and, if it is, it's loaded and the procedure is returned. If no such file exists, the compiler (``csc'') is invoked to create a compiled library (with any extra options passed in OPTIONS), which is stored in the cache. The code will be compiled as if wrapped in #>! ... <#. Note that you will have to shield #include forms, if you don't want them to be processed by the FFI parser:

(inline #<<EOF
#ifndef CHICKEN
#include "gd.h"
#include <stdio.h>

void genimages(int w, int h) {
  gdImagePtr im;
  FILE *pngout, *jpegout;
  int black;
  int white;

  im = gdImageCreate(w, h);
  black = gdImageColorAllocate(im, 0, 0, 0);	
  white = gdImageColorAllocate(im, 255, 255, 255);	
  gdImageLine(im, 0, 0, w - 1, h - 1, white);	
  pngout = fopen("test.png", "wb");
  jpegout = fopen("test.jpg", "wb");
  gdImagePng(im, pngout);
  gdImageJpeg(im, jpegout, -1);
"-L -lgd -L -lpng -L -lz -L -ljpeg -L -lfreetype"
