rasSetOption

BOOL32 __stdcall rasGetOption(IPGC CachePtr, TPageCacheOptions Option, int32_t* Value);
BOOL32 __stdcall rasSetOption(IPGC CachePtr, TPageCacheOptions Option, int32_t Value);

function rasGetOption(CachePtr: IPGC; Option: TPageCacheOptions; var Value: Integer): LongBool; stdcall;
function rasSetOption(CachePtr: IPGC; Option: TPageCacheOptions; Value: Integer): LongBool; stdcall;

Purpose. A generic, extensible per-cache integer option bag, indexed by a TPageCacheOptions enum ordinal — the catch-all configuration mechanism for cache behaviors that don't have their own dedicated ras* getter/setter pair.

Description. Both index into a fixed C.Opts array (bounds-checked 0..63 — Ord(Option) outside that range fails cleanly rather than indexing out of bounds). This chapter did not enumerate every TPageCacheOptions member or trace which ones are actually consulted elsewhere in the rendering/paint pipeline beyond this storage array itself — treat individual option semantics as stored, not independently confirmed effective, consistent with this SDK's recurring "generic option bag with unverified downstream consumption" pattern seen for other catch-all mechanisms.

Parameters.

Return value. True if CachePtr resolves and Option is in range; False otherwise.
