QG_SetCacheSize

QG_SetCacheSize(areaRef; maxCachedBytes):errorCode
	areaRef	Longint	QGrid area reference
	maxCachedBytes	Longint	Maximum cache size in bytes
	error	Longint	Error result

Parameter areaRef is the QGrid area reference. If areaRef is not a valid QGrid area reference, qg_paramErr error is returned.

Parameter maxCachedBytes specifies the plug-in area's maximum cache size in bytes. It must be between 64MB (64 * 1024 * 1024 bytes) and 512MB (512 * 1024 * 1024 bytes), otherwise error qg_paramErr is returned.

NOTE The default cache size for a plug-in area is 128MB (128 * 1024 * 1024 bytes).

Example

   // Double the cache size of the plug-in area

C_LONGINT($cacheSize;$err)

$err:=QG_GetCacheSize (xGrid;$cacheSize)
ASSERT($err=qg_noErr)

$cacheSize:=$cacheSize*2

$err:=QG_SetCacheSize (xGrid;$cacheSize)
ASSERT($err=qg_noErr)
