Detect Overflow

[selimsl]

Hi!

Following code convert ascii desimal data to desimal data

char ascii_array[10]="65535";
unsigned short int datax;			
sscanf(ascii_array,"%u",&datax);

result is: datax->65535
-----------------------------------------

char ascii_array[10]="65536";
unsigned short int datax;			
sscanf(ascii_array,"%u",&datax);

result is: datax->0

Because datax is unsigned short int and an overflow occurs.
Is there any method to detect whether an overflow occurs or not?

Thanks in advice...

Use strtoul()
