-// FixedBuffer provides a simple way to allocate objects within a fixed chunk |
-// of memory. Objects are allocated by calling the |Allocate| method, which |
-// extends the buffer accordingly. Objects allocated in this way are not freed |
-// explicitly. Instead, they remain valid so long as the FixedBuffer remains |
-// valid. The Leak method may be used to steal the underlying memory from the |
-// FixedBuffer. |
-// |
-// Typical usage: |
-// |
-// { |
-// FixedBuffer buf(8 + 8); |
-// |
-// int* a = static_cast<int*>(buf->Allocate(sizeof(int))); |
-// *a = 2; |
-// |
-// double* b = static_cast<double*>(buf->Allocate(sizeof(double))); |
-// *b = 3.14f; |
-// |
-// void* data = buf.Leak(); |
-// Process(data); |
-// |
-// free(data); |
-// } |
