Description:

The dispatch_create_channel() function allocates and initializes a dispatch handle. The attach functions are:

If you wish, you can do a resmgr_attach() with a NULL path. This has the effect of initializing dispatch to receive messages, among other things.

This function is similar to dispatch_create() , but lets you specify a channel for the dispatch to use. It also lets you specify channel flags for name_attach().

Returns:

A handle to a dispatch structure, or NULL if an error occurs.

Note: The dispatch structure, dispatch_t, is an opaque data type; you can't access its contents directly.

Errors:

ENOMEM: Insufficient memory to allocate context.
