fs-mac.so

Shared object that supports Apple Macintosh HFS and HFS Plus (QNX Neutrino)

Syntax:

driver … mac mac_options… &

Runs on:

QNX Neutrino

Options:

There are currently no mac_options defined.

In addition, you can specify any of the filesystem options described for io-blk.so.

Description:

The fs-mac.so shared object provides read-only support for Apple HFS (Hierarchical File System) and HFS Plus. It's automatically loaded by the devb-* drivers when mounting an Apple filesystem.

---

This filesystem uses UTF-8 encoding for presentation of its filenames; attempts to specify a filename not using UTF-8 encoding will fail (with an error of EILSEQ).

---

The slash (/) character (which is valid in file names on the Mac but not in POSIX) is swapped with the colon (:) (which is the Mac path separator). For example, an HFS file called 29/1/2009 will get shown to ls as 29:1:2009, and when opened with that name will internally match back to the 29/1/2009 on-disk name.

The fs-mac.so shared object doesn't support access to the resource fork or hard links.
