DirCreate

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

FUNCTION DirCreate (vRefNum: Integer; parentDirID: LongInt; 
                     directoryName: Str255; 
                     VAR createdDirID: LongInt): OSErr;

vRefNum

A volume reference number, a working directory reference number, or 0 for the default volume.

parentDirID

The directory ID of the parent directory; if it's 0, the new directory
is placed in the root directory of the specified volume.

directoryName

The name of the new directory.

createdDirID

The directory ID of the created directory.

DESCRIPTION

The DirCreate function creates a new directory and returns the directory ID of the new directory in the createdDirID parameter. 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.
