Return Value: void
Description
Parameters
Return Value
This call supports a control on the amount of
filesystem storage used for the DLI graphics
cache. It accepts a low-water and a high-water
mark, in bytes. At document-destroy time (i.e.
when a call to dlpdfdocdestroy is made),
the graphics cache size is evaluated, and if it
exceeds the high-water mark in size, graphics
will be removed from the cache in least recently
used (LRU) order until the cache falls to or
below the low-water mark.
• DLPDFINSTANCE *dliInst: The
DLPDFINSTANCE for which the cache will be
reviewed
• ASUns32 highLimit: The high-water
mark level, in bytes. Exceeding this level will
trigger a purge of graphics in LRU order at
document-destroy time.
• ASUns32 deleteLimit: The low-water
mark level, in bytes, above which graphics
will be purged at document-destroy-time.
Graphics will be removed in LRU order until
the total storage is at or below this figure.
