Prev:	allocate-byte-array ( buffer byte-array -- )
Next:	update-buffer ( buffer-ptr: buffer-ptr size: integer data -- )

Vocabulary

Inputs

buffer	a buffer
target-size	an integer

Outputs
None

Word description
If the buffer-size of the given buffer is less than target-size, reallocates the buffer to a size large enough to accommodate target-size bytes. If the buffer is reallocated, the original contents are lost.
