示例#1

文件： buffer.c 项目： amadvance/tommyds

void buffer_reserve(buffer *b, size_t capacity)
{
  void *data;

  if (capacity > b->capacity)
    {
      capacity = buffer_roundup(capacity);
      data = realloc(b->data, capacity);
      buffer_assert(data != NULL);
      b->data = data;
      b->capacity = capacity;
    }
}

示例#2
