Function string_split

string/std_string.c:2253–2323

* @brief Splits a String object into an array of String objects based on a specified delimiter. * * This function takes a String object and splits it into multiple String objects using the specified delimiter. * The result is an array of String pointers, and the number of resulting splits is stored in the count parameter. * If the input String object, delimiter, or memory allocation fails, the

 * @return An array of String pointers containing the split strings, or NULL if an error occurs.
