Hi Marcelo, In code, there is no language specified reliable way to determine the size of a function. There are a few suspect tricks you could try (such as taking the address of the NEXT function in the source code and subtracting the address of the function of interest), but they are fraught with danger. Outside of the code, try using the "nm" and "objdump" commands to peruse the attributes of your object code. HTH, --Eljay
