- (make-bytevector K [BYTE] [NONGC] [FINALIZE])procedure
Return a newly-allocated bytevector of length K. If the optional fill BYTE is specified, it specifies the initial value for each slot in the bytevector.
The optional arguments NONGC and FINALIZE define whether the vector should be allocated in a memory area not subject to garbage collection and whether the associated storage should be automatically freed (using finalization) when there are no references from Scheme variables and data. NONGC defaults to #t (the vector will be located in non-garbage-collected memory) and FINALIZE defaults to #t. Note that the FINALIZE argument is only used when NONGC is true.
