ibuffer read有效性判断 #88
Description
改成下面的方式，在运行过程中添加有效性判断
virtual int read(T *data, unsigned int size)
{
if (size > m_maxBufferSize)
{
size = m_maxBufferSize;
}
unsigned int readDataSize = 0;
while ((!isEmpty()) && (readDataSize < size))
{
data[readDataSize] = m_buffer[m_head & (m_maxBufferSize - 1)];
++readDataSize;
m_head = (m_head + 1) & m_maxMirrorBufferIndex;
}
return readDataSize;
}
