OSErr PBHOpenRFDenyAsync (
    HParmBlkPtr paramBlock
);

paramBlock

A pointer to a basic HFS parameter block.

function result

A result code.

DISCUSSION

The relevant fields of the parameter block are:

• ioCompletion

  On input, a pointer to a completion function.

• ioResult

  On output, the result code of the function.

• ioNamePtr

  On input, a pointer to a pathname.

• ioVRefNum

  On input, a volume specification.

• ioRefNum

  On output, the file reference number

• ioDenyModes

  On input, access rights data.

• ioDirID

  On input, the directory ID.

The result code opWrErr is returned if you’ve requested write permission and you have already opened the file for writing; in that case, the existing file reference number is returned in ioRefNum. You should not use this reference number unless your application originally opened the file.
