This section gives an alphabetical listing of the connect and I/O function entry points that you can fill in (the two tables passed to resmgr_attach()). Remember that if you simply call iofunc_func_init(), all these entries will be filled in with the appropriate defaults; you'd want to modify a particular entry only if you wish to handle that particular message. In the "Examples" section, below, you'll see some examples of the common functions.
In order not to confuse the client's C-library call (for example, open()) with the resource manager connect outcall that goes into that particular slot, we've given all of our functions an "io_" prefix. For example, the function description for the open connect outcall slot will be under io_open().
