Función termina y devuelve si NULL final de str se encuentra antes de la final' token se encuentra.

stocke les résultats dans une dynamique de tableau; nul de terminaison de la matrice; garde l'entrée de la chaîne de sécurité strtok modifie la chaîne d'entrée, qui est comportement indéfini sur un littéral de type char[], du moins je le pense en C99 Pour rendre le code réentrant, l'utilisation de la non-standard strtok_r. El valor de str se modifica en que cada delimitador encontrado se sobrescribe con un byte cero, otra buena razón para copiar la cadena que se analiza primero. En un comentario, alguien sugirió que strtok es mejor que strsep porque strsep es más portátil.

The strtok_r function is a reentrant version strtok. The saveptr argument is a pointer to a char variable that is used internally by strtok_r in order to maintain context between successive calls that parse the same string. On the first call to strtok_r, str should point to the string to be parsed, and the value of saveptr is ignored. The strtok function uses an internal static pointer to point to the next token in the string being tokenized. A reentrant version of the strtok function, strtok_r, which does not use any internal static storage, can be used in place of the strtok function.

As-tu déjà bien saisie la notion de chaine de. token = strtokstr parses str from left to right, using whitespace characters as delimiters, and returns part or all of the text in token. First, strtok ignores any leading whitespace in str. Then, strtok starts at the first character that is not whitespace, and includes all characters up to,. If such a character is not found, there are no tokens in the string. strtok returns a NULL pointer. The token ends with the first character contained in the string pointed to by string2. If such a character is not found, the token ends at the terminating NULL character. Subsequent calls to strtok.

The strtok_s family of functions finds the next token in str.
