Chapter 20. File System Table
The remaining fields are pointers to functions that implement filesystem operations that apply to files and directories
as whole objects. The operation implemented by each function should be obvious from the names, with a few
exceptions:
The
opendir()
function pointer opens a directory for reading. See
for details.
The
getinfo()
and
setinfo()
function pointers provide support for various minor control and information
functions such as
pathconf()
and
access()
.
With the exception of the
mount()
and
umount()
functions, all of these functions take three standard arguments, a
pointer to a mount table entry (see later) a directory pointer (also see later) and a file name relative to the directory.
These should be used by the filesystem to locate the object of interest.
