* Private nvlist printing interface that allows the caller some control
* over output rendering (as opposed to nvlist_print and dump_nvlist).
* Obtain an opaque nvlist_prtctl_t cookie using nvlist_prtctl_alloc
* (NULL on failure); on return the cookie is set up for default formatting
* and rendering. Quote the cookie in subsequent customisation functions and
* then pass the cookie to nvlist_prt to render the nvlist. Finally,
* use nvlist_prtctl_free to release the cookie.
* For all nvlist_lookup_xxx and nvlist_lookup_xxx_array functions
* we have a corresponding brace of functions that appoint replacement
* rendering functions:
* extern void nvlist_prtctl_xxx(nvlist_prtctl_t,
* void (*)(nvlist_prtctl_t ctl, void *private, const char *name,
* xxxtype value))
* and
* extern void nvlist_prtctl_xxx_array(nvlist_prtctl_t,
* void (*)(nvlist_prtctl_t ctl, void *private, const char *name,
* xxxtype value, uint_t count))
* where xxxtype is the C datatype corresponding to xxx, eg int8_t for "int8"
* and char * for "string". The function that is appointed to render the
* specified datatype receives as arguments the cookie, the nvlist
* member name, the value of that member (or a pointer for array function),
* and (for array rendering functions) a count of the number of elements.
