Re: QNX driver File creation

See "Writing a Resource Manager" in our developers product documentation.

The most common method to register a resource name in the dev pathname space is:
resmgr_attach()

Lots of background for that call and what you have to be able to handle after you make that call are documented in the 
above reference.

Object IDs begin with an object prefix and end with a number. For example, if you enter
artf2345
the application will jump directly to an artifact with the ID artf2345. Some valid object prefixes are:
artf	for an artifact
doc	for a document
page	for a project page
topc	for a discussion topic
wiki	for a wiki page
