`rasInitialize`

Nominally: initialize the page cache's background

BOOL32 __stdcall rasInitialize(IPGC CachePtr, TPDFThreadPriority Priority);

Delphi

function rasInitialize(CachePtr: IPGC; Priority: TPDFThreadPriority): LongBool; stdcall;

Purpose. Nominally: initialize the page cache's background rendering with a given thread priority.

Description. In practice, the entire body is C.Busy := False; Result := True — Priority is accepted but never read. Use rasSetThreadPriority (below) to actually set the cache's stored update/render thread priorities.

Parameters.

Parameter	Description
`CachePtr`	Target page cache — its `Busy` flag is cleared.
`Priority`	Accepted but never read.

Return value. True if CachePtr resolves; False otherwise.
