wow-string-list文件说明

• 项目地址：https://gitee.com/wow-iot/wow-iot7
• 本文件主要功能用于字符串链表相关操作，主要涉及创建、销毁、插入、获取、分隔、格式转换；

初始化与退出:

StringList_T* wow_stringlist_new(void)
{return (StringList_T*)wow_slist_create();	
}
void wow_stringlist_free(StringList_T** pptStrList)
{wow_slist_destroy(pptStrList,slist_free_func);
}

字符串链表添加元素

int wow_stringlist_append(StringList_T* ptStrList, const char *pcElem)
{CHECK_RET_VAL_P(ptStrList,-PARAM_INPUT_STRUCT_IS_NULL,"param input struct invalid!\n");CHECK_RET_VAL_P(pcElem && strlen(pcElem) > 0,-PARAM_INPUT_DATA_IS_NULL,"param input data invalid!\n");int len = strlen(pcElem);char* data = MALLOC(len + 1);CHECK_RET_VAL_P(data,-SYSTEM_MALLOC_FAILED,"malloc data size!\n");memset(data,0,len + 1);memcpy(data,pcElem,len);return wow_slist_insert_tail(ptStrList,data);
}

获取字符串链表元素个数与内容

int wow_stringlist_size(StringList_T* ptStrList)
{return wow_slist_size(ptStrList);
}
char* wow_stringlist_data(StringList_T* ptStrList,int nIdx)
{return (char*)wow_slist_peek_by_index(ptStrList,nIdx);
}

字符串链表元素格式转换

int wow_stringlist_toInt(StringList_T* ptStrList,int nIdx)
{char* data = (char*)wow_slist_peek_by_index(ptStrList,nIdx);CHECK_RET_ABORT(data);return strtol(data,NULL,10);
}float wow_stringlist_toFloat(StringList_T* ptStrList,int nIdx)
{char* data = (char*)wow_slist_peek_by_index(ptStrList,nIdx);CHECK_RET_ABORT(data);return (float)strtod(data,NULL);
}

分割字符串

StringList_T* wow_stringlist_split(char *pcStr, const char *pcDelim)
{StringList_T* ptStrList = wow_stringlist_new();CHECK_RET_VAL_P(ptStrList,NULL, "string_list new failed!\n");char *copy = strdup(pcStr);CHECK_RET_GOTO_P_A(copy,out, "strdup failed!\n");int ret = -1;char *token = strtok(copy, pcDelim);while (token){ret = wow_stringlist_append(ptStrList, token);CHECK_RET_GOTO(ret == 0,out);token  = strtok(NULL, pcDelim);}free(copy);return ptStrList;out:wow_stringlist_free(&ptStrList);free(copy);return NULL;
}
