description: >
|
|
Enable "compression" of arbitrary C function pointers into an unsigned 16-bit
|
|
value. Use together with DUK_OPT_FUNCPTR_ENC16 and DUK_OPT_FUNCPTR_DEC16.
|
|
|
|
Pointers compressed are any C function pointers. Also NULL pointer must
|
|
encode and decode correctly.
|
|
|
|
Currently it is required that NULL encodes to integer 0, and integer
|
|
0 decodes to NULL. No other pointer can be encoded to 0.
|
|
|
|
NOTE: This feature option is currently unimplemented, i.e. Duktape won't
|
|
compress any function pointers at the moment. It might not be necessary
|
|
to support a NULL function pointer (uncertain until taken into use).
