Data structures

The first thing we need to understand is the data structures used to control the operation of the library:

• resmgr_attr_t control structure
• resmgr_connect_funcs_t connect table
• resmgr_io_funcs_t I/O table

And one data structure that's used internally by the library:

• resmgr_context_t internal context block

Later, we'll see the OCB, attributes structure, and mount structure data types that are used with the POSIX-layer libraries.
