More Info

Authorized functions and macros

  • write (man 2 write)
  • malloc (man 3 malloc)
  • free (man 3 free)
  • va_start (man 3 va_start)
  • va_end (man 3 va_end)
  • va_copy (man 3 va_copy)
  • va_arg (man 3 va_arg)

Compilation

  • Your code will be compiled this way:
    $ gcc -Wall -Werror -Wextra -pedantic -std=gnu89 *.c
  • As a consequence, be careful not to push any c file containing a main function in the root directory of your project (you could have a test folder containing all your tests files including main functions)
  • Our main files will include your main header file (main.h): #include main.h
  • You might want to look at the gcc flag -Wno-format when testing with your _printf and the standard printf. Example of test file that you could use:
alex@ubuntu:~/c/printf$ cat main.c 
#include <limits.h>
#include <stdio.h>
#include "main.h"

  • We strongly encourage you to work all together on a set of tests
  • If the task does not specify what to do with an edge case, do the same as printf
