| 65 ** PR_IMPLEMENT | |
| 66 ** DESCRIPTION: | |
| 67 ** These are only for externally visible routines and globals. For | |
| 68 ** internal routines, just use "extern" for type checking and that | |
| 69 ** will not export internal cross-file or forward-declared symbols. | |
| 70 ** Define a macro for declaring procedures return types. We use this to | |
| 71 ** deal with windoze specific type hackery for DLL definitions. Use | |
| 72 ** PR_EXTERN when the prototype for the method is declared. Use | |
| 73 ** PR_IMPLEMENT for the implementation of the method. | |
| 74 ** | |
| 75 ** Example: | |
| 76 ** in dowhim.h | |
| 77 ** PR_EXTERN( void ) DoWhatIMean( void ); | |
| 78 ** in dowhim.c | |
| 79 ** PR_IMPLEMENT( void ) DoWhatIMean( void ) { return; } | |
