 * Purpose: rename macros in the string                                       *

 *                                                                            *

 * Parameters: in        - [IN] the input string                              *

 *             oldmacro  - [IN] the macro to rename                           *

 *             newmacro  - [IN] the new macro name                            *

 *             out       - [IN/OUT] the string with renamed macros            *

 *             out_alloc - [IN/OUT] the output buffer size                    *

 *                                                                            *

 * Return value: SUCCEED - macros were found and renamed                      *

 *               FAIL    - no target macros were found                        *

 *                                                                            *

 * Comments: If the oldmacro is found in input string then all occurrences of *

 *           it are replaced with the new macro in the output string.         *

 *           Otherwise the output string is not changed.                      *

 *                                                                            *
