Trouve le jeton suivant dans une chane d'octets termine par zro point par
str. Les caractres de sparation sont identifis par une chane d'octets termine par zro point par delim .Original:
Finds the next token in a null-terminated byte string pointed to by

Si
str != NULL, la fonction recherche pour le premier caractre qui n'est pas sparateur. Ce caractre est le dbut de la' jeton. Ensuite, la fonction recherche pour le caractre premier sparateur. Ce personnage est la fin de la' jeton. Fonction termine et renvoie NULL si la fin de str est rencontre avant la fin de la' token est trouv. Sinon, un pointeur vers la fin de la' jeton est enregistr dans un emplacement fixe pour les appels suivants. Ce personnage est alors remplace par une valeur NULL caractres et la fonction retourne un pointeur vers le dbut de la' jeton .Original:
If
str != NULL, the function searches for the first character which is not separator. This character is the beginning of the token. Then the function searches for the first separator character. This character is the end of the token. Function terminates and returns NULL if end of str is encountered before end of the token is found. Otherwise, a pointer to end of the token is saved in a static location for subsequent invocations. This character is then replaced by a NULL-character and the function returns a pointer to the beginning of the token.The text has been machine-translated via Google Translate.
