Example usage: #include "CCRTOS.h" OS_FlagID flag; void TaskN (void *pdata) { ... /* Create a flag with auto reset, initial state: 0 */ flag = CoCreateFlag (1, 0); if (result != E_OK) { if (result == E_CREATE_FAIL) { printf("Failed to create a flag!\n"); } } else { printf("Flag ID : %d \n", flag); } ... } Note: None 6.10.2 CoDelFlag() Function Prototype: StatusType CoDelFlag( Description: Delete a certain flag. ); OS_FlagID U8 Parameters: [in] id The ID of a specified flag [in] opt The deleting mode: EVENT_DEL_NO_PEND, Returns: E_INVALID_ID, EVENT_DEL_ANYWAY, E_TASK_WAITING, id, opt Delete when the waiting list is empty. Delete unconditionally. The incoming ID is invalid. The waiting list isn’t empty. 108
E_OK, Example usage: Delete successfully. #include "CCRTOS.h" OS_FlagID flag; void TaskN (void *pdata) { StatusType result; ... /* Delete the Flag */ result = CoDelFlag (flag, OPT_DEL_ANYWAY); if (result != E_OK) { if (result == E_INVALID_ID) { printf("Invalid Flag ID !\n"); } } ... } Note: When you have deleted a flag successfully, the resources it occupied will be released. The system will start a task scheduling then so as to give the execution time to the task which has the highest priority. 6.10.3 CoAcceptSingleFlag() Function Prototype: StatusType CoAcceptSingleFlag( OS_FlagID id ); Description: Request for a single flag without waiting. Parameters: [in] id The ID of a specified flag Returns: E_INVALID_ID, The ID of the incoming flag is invalid. ID E_FLAG_NOT_READY, The flag isn’t in the ready state. E_OK, Obtain the flag successfully. 109
