in thread Solved: How to use 'unsigned char' C data type with Win32::API

Hi tye

I suppose to get like below C code's API call.

# C Code # printf ("\n \n DEV: %d , %c , %x ", i2cGetDeviceAddress(),i2cGetDevi +ceAddress(),i2cGetDeviceAddress()); # # Output: DEV: 70 , F , 46

I used following code get rid of un initialized bytes

$ret = unpack ('C',pack ('i*',$ret)); #This gives 152 but this is not +i want :(
