sprintf not printing 32 bit variables correctly

[deneb]

Hello Experts

I am printing an unsigned 32-bit integer as following:

sprintf(str,"%8X", (unsigned long) sig_pow);

where sig_pow is defined as unigned long itself. But strangely it always prints the upper 2 bytes, i.e., most significant 4 hex characters. Anyone has some idea on what is going wrong?

Thanks

The %X specifier takes an int as argument, so the compiler behaves as expected.

Hi daneb,

I'd suggest you to try:

 sprintf(str,"%8LX",sig_pow);


this might help...
