/**
* \fn int PHYSFS_setBuffer(PHYSFS_file *handle, PHYSFS_uint64 bufsize)
* \brief Set up buffering for a PhysicsFS file handle.
*
* Define an i/o buffer for a file handle. A memory block of (bufsize) bytes
* will be allocated and associated with (handle).
*
* For files opened for reading, up to (bufsize) bytes are read from (handle)
* and stored in the internal buffer. Calls to PHYSFS_read() will pull
* from this buffer until it is empty, and then refill it for more reading.
* Note that compressed files, like ZIP archives, will decompress while
* buffering, so this can be handy for offsetting CPU-intensive operations.
* The buffer isn't filled until you do your next read.
*
* For files opened for writing, data will be buffered to memory until the
* buffer is full or the buffer is flushed. Closing a handle implicitly
* causes a flush...check your return values!
*
* Seeking, etc transparently accounts for buffering.
*
* You can resize an existing buffer by calling this function more than once
* on the same file. Setting the buffer size to zero will free an existing
* buffer.
*
* PhysicsFS file handles are unbuffered by default.
*
* Please check the return value of this function! Failures can include
* not being able to seek backwards in a read-only file when removing the
* buffer, not being able to allocate the buffer, and not being able to
* flush the buffer to disk, among other unexpected problems.
*
* \param handle handle returned from PHYSFS_open*().
