Problème de compilation sur l'initialisation d'un pointeur de structure
Avec le code
Code:

| #include <stdio.h>
struct toto
{
unsigned int key;
char *value;
};
struct toto *key_values_private_ptr = (struct toto *)NULL;
key_values_private_ptr = (struct toto *)NULL; |
J'ai les erreurs suivantes :

Je constate que
Code:
struct toto *key_values_private_ptr = (struct toto *)NULL;
compile sans souci
mais pas
Code:
key_values_private_ptr = (struct toto *)NULL;
J'avoue ne pas comprendre pourquoi...
Bonne journée
