Note: In order to correctly define RESMGR_HANDLE_T, #include <sys/iofunc.h> before <sys/resmgr.h>.

Description:

The resmgr_connect_funcs_t structure is a table of the POSIX-level connect functions that are used by a resource manager. You can initialize this table by calling iofunc_func_init() and then overriding the defaults with your own functions.

This structure includes nfuncs, which indicates how many functions are in the table (in case the structure grows in the future), along with these functions:

Member:	Used to:	Default:
`open`	Handle _IO_CONNECT messages	iofunc_open_default()
`unlink`	Unlink the resource	None
`rename`	Rename the resource	None
`mknod`	Create a filesystem entry point	None
`readlink`	Read a symbolic link	None
`link`	Create a symbolic link	None
`unblock`	Unblock the resource if an operation is aborted	None
`mount`	Mount a filesystem	None
