| Transform a binary file into a C header file. | |
| The binary file is splitted into 16 char strings and rebuild at execution time. | |
| The function buildsc() must be called in your main to rebuild the binary file into the sc C variable. | |
| The length is set in the sc_length variable. | |
| Be carefull, try to avoid compiler code optimization as it will remove all these modifications in the final binary. | |
