string save_value(mixed value)
string save_value(mixed value, int format)
Encode the <value> into a string suitable for restoration with
restore_value() and return it.
The optional <format> argument determines the format of the savefile
to be written:
-1: use the driver's native format (default).
0: original format, used by Amylaar LPMud and LDMud <= 3.2.8 .
1: LDMud >= 3.2.9: no-lambda closures, symbols, quoted arrays
can be saved.
2: LDMUd >= 3.5.0: floats are stored in a different way, which is
more compact and can store the new floats losslessly.
It is recommended to use version 2 or higher.
The created string consists of two lines, each terminated with
a newline character: the first line describes the format used to
save the value in the '#x:y' notation; the second line is the
representation of the value itself.
The format of the encoded value and of the format line matches
the format used by save_object() and restore_object().
Introduced in LDMud 3.2.8.
LDMud 3.2.9 added the saving of non-lambda closures, symbols,
and quoted arrays, using the new savefile format version 1.
LDMud 3.2.10 added the <format> argument.
LDMud 3.5.0 added savefile format version 2.
