[英]How to find an FSRef from a directory ID and a volume number?
Given an FSRef of a directory, one can use FSGetCatalogInfo
to find the volume reference number and the directory ID. 给定目录的FSRef,可以使用
FSGetCatalogInfo
查找卷引用号和目录ID。 Together, these two numbers should be enough to identify the directory. 这两个数字应该足以识别目录。 One way to go the other direction would be use
FSMakeFSSpec( vRefNum, dirID, "\\p", &fileSpec )
and then FSpMakeFSRef( &fileSpec, &dirRef )
. 另一个方向是使用
FSMakeFSSpec( vRefNum, dirID, "\\p", &fileSpec )
,然后使用FSpMakeFSRef( &fileSpec, &dirRef )
。 However, FSMakeFSSpec
and FSpMakeFSRef
are deprecated. 但是,不推荐使用
FSMakeFSSpec
和FSpMakeFSRef
。 I'm wondering whether there is a way to go from vRefNum and dirID to FSRef using functions that are not deprecated. 我想知道是否有一种方法可以使用未弃用的函数从vRefNum和dirID转到FSRef。
I've never used it, but it seems FSResolveNodeID
may do what you want. 我从来没有使用它,但似乎
FSResolveNodeID
可能会做你想要的。 Apple pretty much scrubbed its ADC site clean of everything Carbon so I can't find a link to it. 苹果几乎擦洗了它的ADC网站干净的所有碳,所以我找不到它的链接。 But you can look it up in
Files.h
. 但是你可以在
Files.h
查找它。 Also, it's only available in 10.5 or later. 此外,它仅在10.5或更高版本中可用。
