void friend_message_cb issue with "friend_number" ?

[Artysteel]

Good day,

I am trying to print out the value of a friend, who sent message. No matter what I am trying, can't get it to work. I've looked into your code in other *.c files, and you were printing "uint32_t friend_number" normaly with printf.

How I've tried so far:
#include <inttypes.h> //for PRI and etc

void friend_message_cb(Tox *tox, uint32_t friend_number, TOX_MESSAGE_TYPE type, const uint8_t *message, size_t length, void *user_data){

printf("1: %lu \n", friend_number);
printf("2: %lu \n", (unsigned long)friend_number );
printf("3: %"PRIu32"\n" , (uint32_t) friend_number ) ;

}

That should work. What compiler are you using? What does it print? and have you tried simply %u?

[Artysteel]

GCC. Yes I did. It either prints 0 or 1, depends on what I am using

[GrayHatter]

why do you think that number is wrong?

[Artysteel]

Ah yes, sorry, everything is ok. I managed to figure out that this parameter stands for virtual ID of a friend (not its TOX ID, but an index number in the list)
