read bytes in a buffer

[kani98]

Is there a C/C++ function that will tell how many bytes are valid in a buffer?

[Chris Losinger]

not in general. if it was allocated with GlobalAlloc/HeapAlloc, you can get the size with GlobalSize/HeapSize.

Of course not. That can only be determined by the code that placed those bytes in the buffer to begin with.
