Every pas file will be converted to a .c/.h version in the `hedgewars` folder. In case no output is produced something has gone wrong. |

There are some special file that you need to know |
|
21 |
||
22 |
* project_files/hwc/rtl/fpcrtl.h - contains definitions of external functions defined inside custom pascal units (eg SDLh.pas); |
|
23 |
* hedgewars/pas2cSystem.pas - contains definitions of external functions defined outside our own pascal units (eg png and gl units, bundled with freepascal); |
|
24 |
* hedgewars/pas2cRedo.pas - contains definitions of internal fpc units (provided by the 'rtl') which get a fpcrtl_ prefix. |

If you need to hide portions of code from pas2c just wrap it with `${IFNDEF PAS2C}...{$ENDIF}` |
