32 : * Other stuff...
33 : *
34 : * magic_char - This is the magic char used for mangling. It's
35 : * global. There is a call to lp_mangling_char() in server.c
36 : * that is used to override the initial value.
37 : *
38 : * MANGLE_BASE - This is the number of characters we use for name mangling.
39 : *
40 : * basechars - The set characters used for name mangling. This
41 : * is static (scope is this file only).
42 : *
43 : * mangle() - Macro used to select a character from basechars (i.e.,
44 : * mangle(n) will return the nth digit, modulo MANGLE_BASE).
45 : *
46 : * chartest - array 0..255. The index range is the set of all possible
47 : * values of a byte. For each byte value, the content is a
48 : * two nibble pair. See BASECHAR_MASK below.
49 : *
50 : * ct_initialized - False until the chartest array has been initialized via
51 : * a call to init_chartest().
52 : *
53 : * BASECHAR_MASK - Masks the upper nibble of a one-byte value.
54 : *
55 : * isbasecahr() - Given a character, check the chartest array to see
56 : * if that character is in the basechars set. This is
57 : * faster than using strchr_m().
