我想了解 PC lint 错误 19“无用声明”的解决方案。我正在使用中断向量表,并使用所需参数调用中断。当我运行 PC lint 时,我遇到如下所示的错误 19,有人可以帮助我吗?
ifndef Int_HandlerIndAddr
#define Int_HandlerIndAddr(Isr, CpuNr, IntNr, Prio) Int_HandlerIndAddr2(Isr, CpuNr, IntNr, Prio)
万一
#define Int_HandlerIndAddr2(Isr, CpuNr, IntNr, Prio) \
__asm__ (".ifndef .intr2.entry.include \n"\

在同一个文件中的函数调用如下
Int_HandlerIndAddr(TaskOs_CallTaskApp10ms, 0, ISR_NR_TASK_APP_10MS, ISR_PRIO_TASK_APP_10MS);
Int_HandlerIndAddr(TaskOs_CallTaskApp1ms, 0, ISR_NR_TASK_APP_1MS, ISR_PRIO_TASK_APP_1MS);
PC lint 错误消息如下:
Int_HandlerIndAddr(TaskOs_CallTaskApp100ms, 0, ISR_NR_TASK_APP_100MS, ISR_PRIO_TASK_APP_100MS);
