Handling mount()

Mount requests can provide a very convenient and flexible interface for programs that need to enable and disable components of their resource managers' systems.

The main areas to consider when using and building mount functionality into your resource manager are:

• mount utility
• mount() function call
• mount() callout in the resource manager

These components represent the stream of communication for the mount request. Let's start in the middle with the mount() function call and work our way out.

The mount() function call is at the bottom of the utility and represents a client's access point to the resource manager. The function is implemented in the C library, defined in <sys/mount.h>, and described in the QNX Neutrino C Library Reference.
