Vocabulary

Inputs

buffer	a buffer
size	an integer
initial-data	a c-ptr or f

Outputs
None

Word description
Discards any memory currently held by buffer and reallocates a new memory block of size bytes for it. If initial-data is not f, size bytes are copied from initial-data into the buffer to initialize it; otherwise, the buffer content is left uninitialized.
