将有固定分隔符的字符串分解后存入到字符串数组（C语言）

本文已参与「新人创作礼」活动，一起开启掘金创作之路。

/*******************************************************************

*@function: string_to_string_list * *@param1 [IN]: src_str, 有固定分隔符的字符串 * *@param2 [IN]: delimiter, 分隔符字符 * *@param3 [OUT]: delimiter_count, 出参, 分隔符数量 * *@param4 [OUT]: str_list, 出参，用于存放结果的二位字符串数组，

•           使用完成后需要使用LB_FREE_ARRAY释放数组内存
