I am surprised by GCC (this is ver. 4.2.4, Ubuntu 32 bit Intel) when a function declares a float parameter and it's prototype is missing, the parameters are messed up.
Please see my code below:
The output:
As you see, the set_P function somehow messed up parameters.
***Note: the code does work on SCO with stock compiler on similar h/w.
If I add the function prototype to x1.c
then everything works correctly, no surprises.
My understanding is that compiler allocates longs for longs/integers/shorts and doubles for float/double when passing parametrs by value. Then if receiver function expects a float, it will get first 32 bit, which is OK on Intel. Apparently my understanding is not correct.
The code in many places lacks function prototypes, I wander if I can somehow influence compiler to pass float/double parameters and not mess up. Any ideas?
I need to pass a parameter to a function in a script. My parameter is a string. When I display the parameter within my function, I only get the first word from string I pass in.
How can I make the function receive the whole string (and not terminate at the first space it encounters)?.
