Example usage: #include "CCRTOS.h" OS_EventID mailqueue; int IsrDat; void XXX_IRQHandler(void) { StatusType result; } EnterISR(); // Enter ISR ... IsrDat = 0x12; /* Post a mail to MailQueue that created by other tase */ result = isr_PostQueueMail (mailqueue, &IsrDat); if (result != E_OK) { if (result == E_SEV_REQ_FULL) { printf("Service requst queue is full !\n"); } } ... ExitISR(); // Exit ISR Note: 1)It is used in the interrupt service program. 2) Interrupt service routine can not call CoPostQueueMail()to send message of the queue message ,otherwise the system will lead to confusion. 106
