PBDirCreate

You can use the PBDirCreate function to create a new directory.

FUNCTION PBDirCreate (paramBlock: HParmBlkPtr; async: Boolean): 
                        OSErr;

paramBlock

A pointer to a basic HFS parameter block.

async

A Boolean value that specifies asynchronous (TRUE) or synchronous (FALSE) execution.

-->	ioCompletion	ProcPtr	A pointer to a completion routine.
<--	ioResult	OSErr	The result code of the function.
<->	ioNamePtr	StringPtr	A pointer to a pathname.
-->	ioVRefNum	Integer	A volume specification.
<->	ioDirID	LongInt	A directory ID.

DESCRIPTION

The PBDirCreate function is identical to PBHCreate except that it creates a new directory instead of a file. You can specify the parent of the directory to be created in ioDirID; if it's 0, the new directory is placed in the root directory of the specified volume. The directory ID of the new directory is returned in ioDirID. The date and time of its creation and last modification are set to the current date and time.

Note

A directory ID, unlike a volume reference number or a working directory reference number, is a LongInt value.
