示例1: Pop

* Remove bytes from the stack
*/
void IOStack::Pop(unsigned int bytes_to_remove) {
unsigned int bytes_removed = 0;
BlockVector::iterator iter = m_blocks.begin();
while (iter != m_blocks.end() && bytes_removed != bytes_to_remove) {
MemoryBlock *block = *iter;
bytes_removed += block->PopFront(bytes_to_remove - bytes_removed);
if (block->Empty()) {
m_pool->Release(block);
iter = m_blocks.erase(iter);
} else {
iter++;
}
}
}示例2: Pop
/**
* Remove the first n bytes from the buffer
*/
void IOQueue::Pop(unsigned int n) {
unsigned int bytes_popped = 0;
BlockVector::iterator iter = m_blocks.begin();
while (iter != m_blocks.end() && bytes_popped != n) {
