So why it does work with 0x1FFFFFFFF?

And why BITMASK(32) works?

the 32 is suposed to be masked by the 5 bits too no?

Oh ok thats explain everything now.. yea i was getting that warning but i was ignoring the equal case.. so i cant shift a 32bits variable 32 times...

using 0x1FFFFFFFF works but i dont know if...

Nop it does not work.. i did copy and paste your code and got same result... do you think thats some problem with my mingw? Anyway i cant understand why should i have this behavior x is just the...

Could not get the point..

What is the difference of

uint8_t val = 32;
uint32_t ret;

ret = BITMASK(val); //return 0
ret = BITMASK(32); // return 0xFFFFFFFF

Hi, i have a code where i defined:

#define FULLMASK 0xFFFFFFFF
#define BITMASK(x) (~(FULLMASK<<x))

If i use an uint8_t variable with value 32 the macro returns 0, but if i write...

I was wondering if that would not make use of too much memory, but i guess there is no option. Thank you!

Hmm i was wondering .. how can i "insert" lines on the begin of a file? If i write on a file from the begin it will start overwriting what is already on the file...

Thank you!

Hi... i was going to make myself a program to add headers to .c and .h files, but as i dont want to reinvent the wheel, is there such program on the intertet? As header i mean, a comment with the...

Wow, i would never expect that a compiler it is writen on a previous version of its own language. .. very weird. .... well thank you about the answer!

Any other comments are still accepted!!

I could not find any better topic to ask this. This question is generic and not only related to C programming. If it is not suited to this forum please feel free to remove it.

My question is...

Oh, ok i will make use of that!! Thank you!

Thank you!! It worked You helped a lot!! Actually, it did not complain haha. But thank you.

And laserlight made everything more clear to me!!

Cya

Hmmm .. thats true.. so i would just have to make like this?Yea thats makes sense...



int f1(char *a)
{
return f2(a);
}

Hi, i just want to make sure, Is this correct?


int f1(char *a)
{
return f2(&a);
}

int f2(char *a)
{
