| REVISION HISTORY |
| |
| Description: Created separate header file for cor_h_x. Sync'ed up with the |
| PV header template. Added include to cor_h_x.h for legacy files |
| that include cor_h.h when invoking cor_h_x function. |
| |
| Description: Added cor_h_x2.h in the include section. |
| |
| Description: Removed cnst.h in the Include section. Putting it here confuses |
| Visual C++ when building the unit test. The source code |
| includes cnst.h prior to cor_h.h. |
| |
| Description: Updated copyright year and pathname. |
| |
| Description: Updated function prototype to reflect |
| inclusion of pOverflow flag. |
| |
| Description: Updated template to make it build in Symbian. Updated copyright |
| year. |
| |
| Description: Moved _cplusplus #ifdef after Include section. |
| |

| INCLUDE DESCRIPTION |
| |
| This file contains prototype declaration for cor_h function. |
