Local File Systems
VxWorks provides fast file systems tailored to real-time applications. One file
system is compatible with the MS-DOS ® file system, another with the RT-11 file
system, a third is a “raw disk” file system, a fourth supports SCSI tape devices,
and a fifth supports CD-ROM devices.
C++ Development Support
In addition to general C++ support including the iostream library and the
standard template library, the optional component Wind Foundation Classes
adds the following C++ object libraries:
– VxWorks Wrapper Class library
– Tools.h++ library from Rogue Wave
Shared-Memory Objects (VxMP Option)
The VxMP option provides facilities for sharing semaphores, message queues,
and memory regions between tasks on different processors.
Virtual Memory (Including VxVMI Option)
VxWorks provides both bundled and unbundled (VxVMI) virtual memory
support for boards with an MMU, including the ability to make portions of
memory noncacheable or read-only, as well as a set of routines for virtualmemory
management.
Target-resident Tools
In the Tornado development system, the development tools reside on the host
system; see the Tornado User’s Guide for details. However, a target-resident
shell, module loader and unloader, and symbol table can be configured into
the VxWorks system if necessary.
Utility Libraries
VxWorks provides an extensive set of utility routines, including interrupt
handling, watchdog timers, message logging, memory allocation, string
formatting and scanning, linear and ring buffer manipulations, linked-list
manipulations, and ANSI C libraries.
