Inputs

upload	a buffer-upload-pattern
usage	a buffer-usage-pattern
kind	a buffer-kind
size	an integer
initial-data	a c-ptr or f

Outputs

buffer

a buffer

Word description
Allocates a new buffer object of size bytes. 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. upload, usage, and kind provide hints to the implementation about the expected usage pattern of the buffer as documented in the buffer class documentation.
