C语言-实现字符串中是否包含字串

如果包含返回0，不包含返回1

uint8_t bsp_abit_string_search(uint8_t *src, uint8_t *obj, uint8_t srclen)
{
    uint8_t i = 0;
    uint8_t j = 0;
    uint8_t obj_size = 0;

    obj_siz = strlen(obj);

    if((src == NULL) || (obj == NULL))
        return 1;
    
    for(i = 0; i < srclen; i++)
    {
        if(src[i] == obj[0])
        {
            for(j = 1; j < obj_siz; j++)
            {
                if(src[i + j] != obj[j])
                    break;
            }
            if(j == obj_siz)
                return 0;
        }
        if((i + relay_size) > srclen)
            return 1;
    }
}
