variable parameter list

Posted by gerhardkreuzer on May 28, 2015

Hi,

is there any issue ahead to use variable Parameter lists with FreeRTOS (reentrant, preemptive tasking ...)

Here a sample to Show what I want to do:

void testdelegate(uint8t x, ...) { va_list argPtr; int y,z;

va_start(argPtr, x);
y = va_arg(argPtr, int);
z = va_arg(argPtr, int);
va_end(argPtr);	

}

With best rehards

Gerhard

Provided you have enough stack, you should not have a problem. We use variable argument lists to implement FreeRTOS_printf() in both FreeRTOS+TCP and FreeRTOS+FAT.

Regards.
